Analysis of a Tau Neutrino Origin for the Near-Horizon Air Shower Events Observed by the Fourth Flight of the Antarctic Impulsive Transient Antenna (ANITA)

R. Prechelt, S. A. Wissel, A. Romero-Wolf +65

We study in detail the sensitivity of the Antarctic Impulsive Transient Antenna (ANITA) to possible point source fluxes detected via -lepton-induced air showers. This inve…

Formation of the First Two Black Hole-Neutron Star Mergers (GW200115 and GW200105) from Isolated Binary Evolution

Floor S. Broekgaarden, Edo Berger

In this work we study the formation of the first two black hole-neutron star (BHNS) mergers detected in gravitational waves (GW200115 and GW200105) from massive stars in wide isola…

Investigation of the Physical Origin of Overionized Recombining Plasma in the Supernova Remnant IC 443 with XMM-Newton

Hiromichi Okon, Takaaki Tanaka, Hiroyuki Uchida +4

The physical origin of the overionized recombining plasmas (RPs) in supernova remnants (SNRs) has been attracting attention because its understanding provides new insight into SNR…

Recent Results from VERITAS AGN Observations

Wystan Benbow

VERITAS is one of the world's most sensitive detectors of astrophysical very high energy (VHE; E > 100 GeV) gamma rays. This observatory has operated for ~14 years, and nearly 7,00…

Jets in Magnetically Arrested Hot Accretion Flows: Geometry, Power and Black Hole Spindown

Ramesh Narayan, Andrew Chael, Koushik Chatterjee +2

We present the results of nine simulations of radiatively-inefficient magnetically arrested disks (MADs) across different values of the black hole spin parameter : , $-0…

Rates of Compact Object Coalescences

Ilya Mandel, Floor S. Broekgaarden

Gravitational-wave detections are enabling measurements of the rate of coalescences of binaries composed of two compact objects -- neutron stars and/or black holes. The coalescence…

Explaining the LIGO black hole mass function with field binaries: Revisiting Stellar Evolution at low Metallicity or Invoking Growth via gas accretion?

Mohammadtaher Safarzadeh, Enrico Ramirez-Ruiz

Our understanding of the formation and evolution of binary black holes (BBHs) is significantly impacted by the recent discoveries made by the LIGO/Virgo collaboration. Of utmost im…

Constraining Black Hole Spin based on the Absence of Lense-Thirring Precession of Megamaser Clumps

Santiago Giner, Abraham Loeb

We make use of the absence of Lense-Thirring precession of the innermost megamaser clumps around black holes in order to place upper limits on the spin amplitude of seven black hol…

Probing neutrino emission at GeV energies from compact binary mergers with the IceCube Neutrino Observatory

IceCube Collaboration, R. Abbasi, M. Ackermann +415

The advent of multi-messenger astronomy has allowed for new types of source searches by neutrino detectors. We present the results of the search for 0.5-100 GeV astrophysical neutr…

Machine-Learned Dark Matter Subhalo Candidates in the 4FGL-DR2: Search for the Perturber of the GD-1 Stream

Nestor Mirabal, Ana Bonaca

The detection of dark matter subhalos without a stellar component in the Galactic halo remains a challenge. We use supervised machine learning to identify high-latitude gamma-ray s…

Constraining neutron star radii in black hole-neutron star mergers from their electromagnetic counterparts

Giacomo Fragione, Abraham Loeb

Mergers of black hole (BH) and neutron star (NS) binaries are of interest since the emission of gravitational waves (GWs) can be followed by an electromagnetic (EM) counterpart, wh…
