On the sum of eccentric subgraph numbers of the vertices of a connected graph
Akash De, Kamal Lochan Patra
Let be a connected graph. The eccentric subgraph number of a vertex of is defined as , where is the number of connec…
SLSim: a strong lensing population simulation package
Narayan Khadka, Simon Birrer, Henry Best +45
Gravitational lensing offers unique insights into cosmology by bending light around massive objects. Strong gravitational lensing, in particular, produces magnified and often multi…
The Advanced X-ray Imaging Satellite (AXIS) Community Science Book
Michael Koss, Nafisa Aftab, Steven W. Allen +395
The AXIS Community Science Book represents the collective effort of 592 scientists worldwide to define the transformative science enabled by the Advanced X-ray Imaging Satellite (A…
Amoeba: An AGN Model of Optical Emissions Beyond steady-state Accretion discs
Henry Best, Matthew O'Dowd, Joshua Fagin +2
Active Galactic Nuclei (AGN) are objects located in the heart of galaxies which emit powerful and complex radiation across the electromagnetic spectrum. Understanding AGN has becom…
Joint Modeling of Quasar Variability and Accretion Disk Reprocessing using Latent Stochastic Differential Equations
Joshua Fagin, James Hung-Hsu Chan, Henry Best +5
Quasars are bright active galactic nuclei powered by the accretion of matter around supermassive black holes at the center of galaxies. Their stochastic brightness variability depe…
Reverberation Mapping of Lamp-post and Wind Structures in Accretion Thin Disks
James Hung-Hsu Chan, Joshua Fagin, Henry Best +1
To address the discrepancy where disk sizes exceed those predicted by standard models, we explore two extensions to disk size estimates within the UV/optical wavelength range: disk…
Predicting High-magnification Events in Microlensed Quasars in the Era of LSST using Recurrent Neural Networks
Joshua Fagin, Eric Paic, Favio Neira +6
Upcoming widefield surveys, such as the Rubin Observatory's Legacy Survey of Space and Time (LSST), will monitor thousands of strongly lensed quasars over a 10 yr period. Many of t…
Measuring the Substructure Mass Power Spectrum of 23 SLACS Strong Galaxy-Galaxy Lenses with Convolutional Neural Networks
Joshua Fagin, Georgios Vernardos, Grigorios Tsagkatakis +3
Strong gravitational lensing can be used as a tool for constraining the substructure in the mass distribution of galaxies. In this study we investigate the power spectrum of dark m…
On stellar-mass black hole mergers in AGN disks detectable with LIGO
B. McKernan, K. E. S. Ford, J. Bellovary +9
Black hole mergers detectable with LIGO can occur in active galactic nucleus (AGN) disks. Here we parameterize the merger rates, the mass spectrum and the spin spectrum of black ho…
