Description

 

Abstract:

I will present three recent papers advancing our understanding of astrophysics and cosmology. The covered papers are:
I)  arXiv:2304.0607: "The Image of the M87 Black Hole Reconstructed with PRIMO"
   A crisper image of the supermassive black hole of M87 with machine learning


II)  arXiv:2304.09895: "Anomalies in Gravitational-Lensed Images Revealing Einstein Rings Modulated by Wavelike Dark Matter"
   Using strong gravitational lensing to discriminate between fuzzy and WIMP-like dark matter
 

III) arXiv:2304.10934: "A Cross-correlation Study between IceCube Neutrino Events and the Fermi Unresolved Gamma-ray Sky"
    Where do all the very-high-energy neutrinos detected by IceCube come from?
