The possible long-term periodic variability of the extremely luminous quasar WISE J090924.01+000211.1

Takashi Horiuchi, Yoshiki Toba, Toru Misawa +11

The extremely luminous infrared galaxy (ELIRG), WISE J090924.01+000211.1 (hereafter; WISE J0909+0002, ) is an extraordinary object with a quasar aspect. This study performs…

M87: a cosmic laboratory for deciphering black hole accretion and jet formation

Kazuhiro Hada, Keiichi Asada, Masanori Nakamura +1

Over the past decades, there has been significant progress in our understanding of accreting supermassive black holes (SMBHs) that drive active galactic nuclei (AGNs), both from ob…

Macroscopic magnetization of primordial plasma by virial shocks

Uri Keshet, Kuan-Chou Hou

Galaxy-cluster virial (structure-formation accretion) shock observations are shown to imply magnetization of a layer extending Debye lengths downstrea…

How do supernova remnants cool? II. Machine learning analysis of supernova remnant simulations

P. Smirnova, E. I. Makarenko, S. D. Clarke +4

About 15%-60% of all supernova remnants are estimated to interact with dense molecular clouds. In these high density environments, radiative losses are significant. The cooling rad…

The thermodynamic structure and large-scale structure filament in MACS J0717.5+3745

J. P. Breuer, N. Werner, T. Plšek +12

We present the results of Chandra and XMM-Newton X-ray imaging and spatially resolved spectroscopy, as well as new MUSTANG2 90 GHz observations of the thermal Sunyaev-Zeldovich eff…

Actinide signatures in low electron fraction kilonova ejecta

Quentin Pognan, Meng-Ru Wu, Gabriel Martínez-Pinedo +4

Neutron star (NS) mergers are known to produce heavy elements through rapid neutron capture (r-process) nucleosynthesis. Actinides are expected to be created solely by the r-proces…

Evolution and the quasistationary state of collective fast neutrino flavor conversion in three dimensions without axisymmetry

Manu George, Zewei Xiong, Meng-Ru Wu +1

We investigate in this work the evolution of the collective fast neutrino flavor conversion (FFC) in a three dimensional (3D) cubic box with periodic boundary condition for three d…

Jet Collimation and Acceleration in the Flat Spectrum Radio Quasar 1928+738

Kunwoo Yi, Jongho Park, Masanori Nakamura +2

Using time-resolved multifrequency Very Long Baseline Array data and new KaVA (KVN and VERA Array) observations, we study the structure and kinematics of the jet of the flat spectr…

Robust integration of fast flavor conversions in classical neutrino transport

Zewei Xiong, Meng-Ru Wu, Manu George +1

The quantum kinetic evolution of neutrinos in dense environments, such as the core-collapse supernovae or the neutron star mergers, can result in fast flavor conversion (FFC), pres…

Strong lensing of tidal disruption events: Detection rates in imaging surveys

K. Szekerczes, T. Ryu, S. H. Suyu +3

Tidal disruption events (TDEs) are multi-messenger transients in which a star is tidally destroyed by a supermassive black hole at the center of galaxies. The Rubin Observatory Leg…

Fast neutrino flavor conversions in a supernova: Emergence, evolution, and effects

Zewei Xiong, Meng-Ru Wu, Manu George +4

Fast flavor conversions (FFCs) of neutrinos, which can occur in core-collapse supernovae (CCSNe), are multiangle effects. They depend on the angular distribution of the neutrino's…

Multidimensional Radiation Hydrodynamics Simulations of Supernova 1987A Shock Breakout

Wun-Yi Chen, Ke-Jung Chen, Masaomi Ono

Shock breakout is the first electromagnetic signal from supernovae (SNe), which contains important information on the explosion energy and the size and chemical composition of the…

Excess cataloged X-ray and radio sources at galaxy-cluster virial shocks

Gideon Ilani, Kuan-Chou Hou, Uri Keshet

We detect a highly significant excess of X-ray (2RXS) and radio (NVSS, GMRT, VLSSr) catalog sources when stacked around MCXC galaxy clusters and groups, narrowly confined within $\…

A blind search for intraday gamma-ray transients with Fermi-LAT: Detections of GRB and solar emissions

D. A. Prokhorov, A. Moraghan

We present a search for intraday transient gamma-ray signals using 15.4 years of the Fermi Large Area Telescope data. The search is based on a recently developed variable-size slid…
