The Crab Nebula serves as a unique laboratory for studying the acceleration of electrons and positrons through their non-thermal radiation. In this contribution, I would like to present the first fully self-consistent analysis of the Crab Nebula’s γ-ray emission over five orders of magnitude in energy (from 1 GeV to ∼100 TeV). By combining 11.4 years of data from the Fermi Large Area Telescope...
Excess of gamma rays with a spherical morphology around the Galactic center (GC) at GeV energies observed in the Fermi-LAT data is one of the most intriguing features in the gamma-ray sky as it is consistent with annihilation of dark matter particles. Astrophysical explanations include a population of millisecond pulsars (MSPs). We use machine learning algorithms to search for MSP candidates...
Pulsars are highly magnetised, rapidly rotating neutron stars that emit beams of electromagnetic radiation from their magnetic poles and are remarkable laboratories for testing theories of gravity, studying neutron star interiors, and constraining equations of state. Previous surveys searching for such intriguing objects have provided high-impact science results, and new-generation radio...
The Galactic Centre is a region filled with non-thermal astrophysical phenomena, making it a prime target for cutting-edge research using advanced radio telescopes. Using the capabilities of the MeerKAT S-Band receiver, our research is dedicated to finding pulsars within this complex region.
Pulsars, the highly magnetized, rotating neutron stars, are expected to be abundant in the Galactic...
We present an investigation of the L-band emission from known massive young stellar objects (MYSOs) in the SARAO MeerKAT Galactic Plane Survey to search for non-thermal radio emitters from the sample. A total of 398 massive protostars, identified from the Red MSX Source (RMS) survey, are located within the survey region. Among these, 164 fields that host the protostars are isolated from nearby...
A significant fraction of the highest energy gamma-ray astrophysical sources observed are associated with Pulsar Wind Nebulae (PWNe). Given recent observations, the postulated, but unverified, hadronic component from PWNe requires renewed attention in the long search for PeVatrons. We estimate possible ranges for the average pulsar pair production multiplicity on 31 sources in the Australia...
