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

Autor: Ulrich, Yannick, Croon, Djuna, Sakstein, Jeremy, McDermott, Samuel

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 pulsational pair-instability supernovae (PPISN). Our formalism enables

WavPool: A New Block for Deep Neural Networks

Autor: McDermott, Samuel D., Voetberg, M., Nord, Brian

Modern deep neural networks comprise many operational layers, such as dense or convolutional layers, which are often collected into blocks. In this work, we introduce a new, wavelet-transform-based network architecture that we call the multi-resoluti

Astrophysical and Cosmological Probes of Dark Matter

Autor: Boddy, Kimberly K., Lisanti, Mariangela, McDermott, Samuel D., Rodd, Nicholas L., Weniger, Christoph, Ali-Haïmoud, Yacine, Buschmann, Malte, Cholis, Ilias, Croon, Djuna, Erickcek, Adrienne L., Gluscevic, Vera, Leane, Rebecca K., Mishra-Sharma, Siddharth, Muñoz, Julian B., Nadler, Ethan O., Natarajan, Priyamvada, Price-Whelan, Adrian, Vegetti, Simona, Witte, Samuel J.

While astrophysical and cosmological probes provide a remarkably precise and consistent picture of the quantity and general properties of dark matter, its fundamental nature remains one of the most significant open questions in physics. Obtaining a m

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

Autor: Cholis, Ilias, Zhong, Yi-Ming, McDermott, Samuel D., Surdutovich, Joseph P.

Publikováno v: Phys. Rev. D 105, 103023 (2022)

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 first producing a new set of high-resolution galactic diffuse gamma-r
