The Dark Matter Discovery Potential of the Advanced Particle-Astrophysics Telescope (APT)

Fei Xu, Dan Hooper

Gamma-ray observations of Milky Way dwarf galaxies have been used to place stringent constraints on the dark matter's annihilation cross section. In this paper, we evaluate the sen…

DIGS: Deep Inference of Galaxy Spectra with Neural Posterior Estimation

Gourav Khullar, Brian Nord, Aleksandra Ciprijanovic +2

With the advent of billion-galaxy surveys with complex data, the need of the hour is to efficiently model galaxy spectral energy distributions (SEDs) with robust uncertainty quanti…

Modified gravitational wave propagation with higher modes and its degeneracies with lensing

Jose Maria Ezquiaga, Wayne Hu, Macarena Lagos +2

Low-energy alternatives to General Relativity (GR) generically modify the phase of gravitational waves (GWs) during their propagation. As detector sensitivities increase, it become…

The Contribution From TeV Halos to the Isotropic Gamma-Ray Background

Fei Xu, Dan Hooper

Recent observations have shown that pulsars are surrounded by extended regions which emit TeV-scale gamma rays through the inverse Compton scattering of very high energy electrons…

Please repeat: Strong lensing of gravitational waves as a probe of compact binary and galaxy populations

Fei Xu, Jose Maria Ezquiaga, Daniel E. Holz

Strong gravitational lensing of gravitational wave sources offers a novel probe of both the lens galaxy and the binary source population. In particular, the strong lensing event ra…

The Evolution of Chemical Abundance in Quasar Broad Line Region

Fei Xu, Fuyan Bian, Yue Shen +3

We study the relation between the metallicity of quasar broad line region (BLR) and black hole (BH) mass () and quasar bolometric luminosit…
