Multi-Generational Black Hole Population Analysis with an Astrophysically Informed Mass Function

Yannick Ulrich, Djuna Croon, Jeremy Sakstein +1

We analyze the population statistics of black holes in the LIGO/Virgo/KAGRA GWTC-3 catalog using a parametric mass function derived from simulations of massive stars experiencing p…

A Phantom Menace: On the Morphology of the Galactic Center Excess

Samuel D. McDermott, Yi-Ming Zhong, Ilias Cholis

The characteristics of the Galactic Center Excess (GCE) emission observed in gamma-ray energies -- especially the morphology of the GCE -- remain a hotly debated subject. The manne…

The Return of the Templates: Revisiting the Galactic Center Excess with Multi-Messenger Observations

Ilias Cholis, Yi-Ming Zhong, Samuel D. McDermott +1

The Galactic center excess (GCE) remains one of the most intriguing discoveries from the Fermi Large Area Telescope (LAT) observations. We revisit the characteristics of the GCE by…

Analyzing the Gamma-ray Sky with Wavelets

Bhaskaran Balaji, Ilias Cholis, Patrick J. Fox +1

We analyze the gamma-ray sky at energies of 0.5 to 50 GeV using the undecimated wavelet transform on the sphere. Focusing on the inner of the sky, we…

Wavelet-Based Techniques for the Gamma-Ray Sky

Samuel D. McDermott, Patrick J. Fox, Ilias Cholis +1

We demonstrate how the image analysis technique of wavelet decomposition can be applied to the gamma-ray sky to separate emission on different angular scales. New structures on sca…
