Population properties and multimessenger prospects of neutron star-black hole mergers following GWTC-3

Kavli Affiliate: Salvatore Vitale | First 5 Authors: Sylvia Biscoveanu, Philippe Landry, Salvatore Vitale, , | Summary: Neutron star-black hole (NSBH) mergers detected in gravitational-waves have the potential to shed light on supernova physics, the dense matter equation of state, and the astrophysical processes that power their potential electromagnetic counterparts. We use the population of […]

Independent Evidence for earlier formation epochs of fossil groups of galaxies through the intracluster light: the case for RX J100742.53+380046.6

Kavli Affiliate: Eric Miller | First 5 Authors: Renato A. Dupke, Yolanda Jimenez-teja, Yuanyuan Su, Eleazar R. Carrasco, Anton M. Koekemoer | Summary: Fossil groups (FG) of galaxies still present a puzzle to theories of structure formation. Despite the low number of bright galaxies, they have relatively high velocity dispersions and ICM temperatures often corresponding […]

Hard X-ray emission from the eastern jet of SS 433 powering the W50 `Manatee’ nebula: Evidence for particle re-acceleration

Kavli Affiliate: Melania Nynka | First 5 Authors: Samar Safi-Harb, Brydyn Mac Intyre, Shuo Zhang, Isaac Pope, Shuhan Zhang | Summary: We present a broadband X-ray study of W50 (`the Manatee nebula’), the complex region powered by the microquasar SS 433, that provides a test-bed for several important astrophysical processes. The W50 nebula, a Galactic […]

Poisson brackets in Sobolev spaces: a mock holonomy-flux algebra

Kavli Affiliate: J. S. Villasenor | First 5 Authors: J Fernando Barbero G, Marc Basquens, Bogar Díaz, Eduardo J S Villaseñor, | Summary: The purpose of this paper is to discuss a number of issues that crop up in the computation of Poisson brackets in field theories. This is specially important for the canonical approaches […]

Unraveling the interplay between SIDM and baryons in MW halos: defining where baryons dictate heat transfer

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Jonah C. Rose, Paul Torrey, Mark Vogelsberger, Stephanie O’Neil, | Summary: We present a new set of cosmological zoom-in simulations of a MW-like galaxy which for the first time include elastic velocity-dependent self interacting dark matter (SIDM) and IllustrisTNG physics. With these simulations we investigate the interaction […]

Black holes: Timing and spectral properties and evolution

Kavli Affiliate: Erin Kara | First 5 Authors: Emrah Kalemci, Erin Kara, John A. Tomsick, , | Summary: We review the timing and spectral evolution of black hole X-ray binary systems, with emphasis on the current accretion-ejection paradigm. When in outburst, stellar mass black hole binaries may become the brightest X-ray sources in the sky. […]

The TESS-Keck Survey. XIII. An Eccentric Hot Neptune with a Similar-Mass Outer Companion around TOI-1272

Kavli Affiliate: George R. Ricker | First 5 Authors: Mason G. MacDougall, Erik A. Petigura, Tara Fetherolf, Corey Beard, Jack Lubin | Summary: We report the discovery of an eccentric hot Neptune and a non-transiting outer planet around TOI-1272. We identified the eccentricity of the inner planet, with an orbital period of 3.3 d and […]

An Injection System for the CHIME/FRB Experiment

Kavli Affiliate: Kiyoshi W. Masui | First 5 Authors: Marcus Merryfield, S. P. Tendulkar, Kaitlyn Shin, Bridget C. Andersen, Alexander Josephy | Summary: Dedicated surveys searching for Fast Radio Bursts (FRBs) are subject to selection effects which bias the observed population of events. Software injection systems are one method of correcting for these biases by […]

The Tidal Disruption Event AT2021ehb: Evidence of Relativistic Disk Reflection, and Rapid Evolution of the Disk-Corona System

Kavli Affiliate: Dheeraj R. Pasham | First 5 Authors: Yuhan Yao, Wenbin Lu, Muryel Guolo, Dheeraj R. Pasham, Suvi Gezari | Summary: We present X-ray, UV, optical, and radio observations of the nearby ($approx78$ Mpc) tidal disruption event (TDE) AT2021ehb/ZTF21aanxhjv during its first 430 days of evolution. AT2021ehb occurs in the nucleus of a galaxy […]

The complex dynamical past and future of double eclipsing binary CzeV343: misaligned orbits and period resonance

Kavli Affiliate: Michael M. Fausnaugh | First 5 Authors: Ondřej Pejcha, Pavel Cagaš, Camille Landri, Michael M. Fausnaugh, Gisella De Rosa | Summary: CzeV343 was previously identified as a candidate double eclipsing binary (2+2 quadruple), where the orbital periods of the two eclipsing binaries ($P_A approx 1.2$ days and $P_B approx 0.8$ days) lie very […]
