Neutrino Constraints on memory-burdened Primordial Black Holes from Dwarf Spheroidal Galaxies
Xiu-Hui Tan, Jun-qing Xia, Yu-Feng Zhou
Dwarf spheroidal galaxies (dSphs) represent prime targets for indirect dark matter (DM) searches due to their substantial DM content and low astrophysical backgrounds. In this work…
Constraints on Primordial Magnetic Fields from High Redshift Stellar Mass Density
Qile Zhang, Shang Li, Xiu-Hui Tan +1
Primordial magnetic fields (PMFs) play a pivotal role in influencing small-scale fluctuations within the primordial density field, thereby enhancing the matter power spectrum withi…
Revisiting Bounds on Primordial Black Hole as Dark Matter with X-ray Background
Xiu-hui Tan, Jun-qing Xia
Within the mass range of g, primordial black holes (PBHs) persist as plausible candidates for dark matter. Our study involves a reassessment of the constr…
Searching for Signal of Primordial Black Hole from CMB Lensing and -ray Emissions
Xiu-Hui Tan, Yang-Jie Yan, Taotao Qiu +1
In this , we search for the signal of the primordial black holes (PBHs) by correlating the -ray emissions in the MeV energy band produced by the Hawking evapora…
Searching for Integrated Sachs-Wolfe Effect from Fermi-LAT Diffuse -ray Map
Xiu-Hui Tan, Ji-Ping Dai, Jun-Qing Xia
In this paper, we estimate the cross-correlation power spectra between the Planck 2018 cosmic microwave background (CMB) temperature anisotropy map and the unresolved -ray backg…
Bounds on WIMP dark matter from galaxy clusters at low redshift
Xiuhui Tan, Manuel Colavincenzo
The study of the cross-correlation angular power spectrum between gravitational tracers and electromagnetic signals can be a powerful tool to constrain Dark Matter (DM) microscopic…
Searching for gamma-ray emission from galaxy clusters at low redshift
Manuel Colavincenzo, Xiuhui Tan, Simone Ammazzalorso +4
We report the identification of a positive cross-correlation signal between the unresolved -ray emission, measured by the \emph{Fermi} Large Area Telescope, and four different g…
