Beyond the standard: transient phenomena at low X-ray luminosity state & LGTBIQA+ initiatives at ESA and the Spanish Astronomical Society

• Alicia Rouco Escorial (ESAC Madrid, Accreting neutron stars - X-ray astronomy)

In this talk I will introduce two topics that are objectively unrelated, but subjectively very close to each other in my heart: science and diversity, equity and inclusion matters. On one hand, X-ray studies are a useful and powerful tool to disentangle the diverse physics behind the observed transient phenomena such as those in Be/X-ray binaries (BeXBs) and gamma-ray bursts (GRBs). Be/X-ray transients are high-mass X-ray binaries which harbour Be-type stars and highly magnetised neutron stars. While these systems have been intensely observed and studied during outburst, not much is known about their 'not-in-outburst' state, i.e. at low X-ray luminosities. I will present the different scenarios proposed to explain the X-ray behaviour shown by BeXBs during this state, from low-level accretion to crustal cooling of the neutron star, and the role played by the high magnetic field of the neutron star in these scenarios. On the other hand, GRBs show some of the most energetic transient phenomena in the Universe. Their synchrotron emission allows for multi-wavelength studies where the joint power of X-ray and optical observations reveals information about the energetics, jet opening angles, environments and progenitor channels of these events. In general, two different progenitor channels have been proposed and demonstrated depending on the GRB duration, either double neutron-star mergers (short GRBs) or the collapse of massive stars (long GRBs). I will introduce our lates study of late X-ray afterglow detection of SGRBs. This allows us to infer the rate of neutron star-neutron star mergers and compare it with the current rates obtained from the LIGO/VIRGO/KAGRA collaboration and galactic studies.

Order and Number, A Route to Quantum Gravity

• Sumati Surya (Raman Research Institute, Quantum Gravity)

One of the very many open problems in theoretical physics is that of quantising gravity, which is the attempt to successfully combine general relativity and quantum theory. In this talk I will give a broad overview of the problem of quantum gravity and the choices that we can make, along the routes we take. This will lead me to the poset-based "causal set" approach to quantisation. This is a discrete, Lorentzian, sum-over-histories formulation which combines the "essence" of Lorentzian geometry with UV finiteness. In the continuum approximation of the theory, the order relation corresponds to causality while cardinality or number corresponds to spacetime volume. I will describe elements of this theory and where it has led us in our search for a non-perturbative theory of quantum gravity.

Breaking Barriers: Advancing Diversity and Inclusion in Astronomy and Astrophysics Across Europe

• Cosimo Inserra (Cardiff University, Astronomy and Astrophysics)

Diversity and inclusion are essential for fostering innovation and progress in any scientific field. However, the disciplines of astronomy and astrophysics in Europe continue to face significant challenges in achieving equitable representation of different genders, ethnicities, and socioeconomic backgrounds. This talk will present an analysis of the current state of diversity within these fields, drawing on recent data from European institutions. I will explore both the visible and systemic barriers that hinder full participation, ranging from implicit biases in hiring practices to limited opportunities for early-career scientists from underrepresented groups. Furthermore, I will highlight promising initiatives aimed at addressing these disparities, such as mentoring networks, inclusive policies in research funding, and strategies for creating a more supportive academic environment.

Constructing a consistent and computable quantum space-time

• Seth Asante (University of Jena, Quantum Gravity)

Einstein’s theory of general relativity successfully describes gravitation by providing dynamics for the geometry of space-time continuum. However, at small scales or in extreme conditions, the smooth structure of space-time breaks down and must be replaced by a notion of quantum space-time. In this talk, I will present a framework for constructing a notion of ‘quantum geometry’, whose dynamics determine the properties of a quantum space-time and is expected to be consistent over all scales. I will focus on simple models to illustrate such a construction, highlighting the key principles and challenges involved in building a computable quantum space-time.

The physics and mathematics of wound healing

• Tanniemola Liverpool (University of Bristol, Biophysics)

I will discuss some recent work looking quantitatively at the process of wound healing using ideas from thermodynamics and statistical mechanics. Wound healing is a highly conserved process required for survival of an animal after tissue damage. The wound repair process is not only of great interest in its own right but is also a laboratory to study complex tissue dynamics and regeneration. Many wounds involve damage to an epithelial (barrier) tissue (like skin) that separates different regions of the body of a living organism. I will describe some recent work on studying wound healing in two dimensional epithelial tissues of a fruit fly pupal wing. This epithelium was chosen because it is transparent and accessible to sophisticated imaging techniques. We use live confocal time-lapse microscopy to follow the behaviour of cells in a tissue before and after wounding. I will focus on three cell-behaviours that are generally accepted to contribute to wound re-epithelialisation: cell shape deformation, cell division, and cell migration. I will describe how we are beginning to use a combination of mathematics, physics and biology to disentangle some of the organising principles behind the complex orchestrated dynamics that lead to wound healing. https://people.maths.bris.ac.uk/~matbl/

Why Word (Form) Choice Matters: Linguistic Perspectives on Gender-Inclusive Language

• Miriam Zapf (FAU Erlangen-Nürnberg, Linguistics)

In recent years, the issue of gender-inclusive language use has ignited increasingly controversial debates across various countries and language communities. In languages with grammatical gender, this particularly concerns the use of alternative forms for so-called masculine generic terms. While some argue that the gendered meaning of masculine forms can be neutralized – allowing these terms to refer to individuals regardless of gender –, others state that masculine forms are primarily associated with persons of male gender in cognitive processing. This talk aims to shed light on how insights from linguistic research can contribute to a more nuanced understanding of this topic. We will begin by defining what ‘gender-inclusive language use’ entails and exploring some gender-inclusive language forms currently under discussion in languages such as German, Spanish, and French. We will then critically examine common arguments for and against gender-inclusive language use from a linguistic point of view, drawing on findings from recent psycholinguistic research. Finally, we will identify areas that warrant further investigation and discuss some societal questions that remain to be addressed.

Beyond Brownian diffusion

• Flavio Seno (University of Padova, Condensed Matter Physics)

In this seminar, I will illustrate why, more than 100 years after Einstein's fundamental work on Brownian motion, this topic is still debated. In particular, I will discuss some of its anomalies and focus on what is defined as Brownian but non-Gaussian behavior. I will highlight the possible biological advantages of this phenomenon. In the last part of the seminar, I will talk about gender, inclusion, and diversity policies at the University of Padua and in my Department.

Physics, Palsy and Pliės

• Patricia Pyrka (Canda's National Ballet School Toronto)

Despite revolutionary social and technological changes in the past decades, the "what do I want to do when I grow up" approach to life still dominates our thinking: Go to school, get a degree or vocational training, start working, build more and more expertise in your field, climb the corporate or academic ladder, retire, and then enjoy life. Such a life path may feel secure and predictable and promises reputational and financial growth. But what if your interests change? Or if life throws unexpected things at you, or your abilities require a different approach? What if you discover hidden talents at a later stage of life? In her talk, Patricia challenges the single-track trajectory through life by telling her own story - which took her from being a physicist, working in professional hockey, becoming a mother to a disabled child, to unexpectedly starting ballet at age 37 and now, ten years later, getting her teaching diploma from Canada's National Ballet School. Patricia will also speak about her experiences as a caregiver to her now 18-year-old disabled son, and why the educational system and the participatory aspect of life made them decide to move from Germany to Canada. Patricia shares her conclusions from this path and postulates that different stages in life, as well as our unique responsibilities and abilities, may not only benefit from but require new expressions of our selves. She will also touch upon how integrating our personal tragedies and pains into those expressions can deepen them and allow us to become more responsive and less attached to one particular way or the other.

Roundtable Discussion: Supporting People with Special Needs in Education and Research This roundtable discussion focuses on improving accessibility in education and research for individuals with special needs, in both educational settings and research environments. Participants will explore how the physics and beyond community can create more inclusive spaces by addressing physical, sensory, and cognitive barriers. Through shared personal experiences and reflections, the discussion aims to identify actionable solutions to enhance access and participation for people with disabilities. The conversation will encourage open dialogue, fostering a collaborative atmosphere where practical strategies can be developed to ensure everyone has equal opportunities to succeed in education and research . Discussion Participants: Patricia Pyrka (Canada's National Ballet School Toronto) Matti Wetzel (University of Vienna)
