A geomagnetic filter for the Fermi-LAT background
D. A. Prokhorov, A. Moraghan
One of the unsolved questions in gamma-ray astronomy is whether the extragalactic gamma-ray background is of the discrete-source origin. To respond to this question, one first need…
Kinematics of the M87 jet in the collimation zone: gradual acceleration and velocity stratification
Jongho Park, Kazuhiro Hada, Motoki Kino +36
We study the kinematics of the M87 jet using the first year data of the KVN and VERA Array (KaVA) large program, which has densely monitored the jet at 22 and 43 GHz since 2016. We…
Neutrino Production Associated with Late Bumps in Gamma-Ray Bursts and Potential Contribution to Diffuse Flux at IceCube
Gang Guo, Yong-Zhong Qian, Meng-Ru Wu
IceCube has detected many TeV--PeV neutrinos, but their astrophysical origins remain largely unknown. Motivated by the observed late-time X-ray/optical bumps in some gamma-ray burs…
An X-ray Detection of Star Formation In a Highly Magnified Giant Arc
M. B. Bayliss, M. McDonald, K. Sharon +19
In the past decade, our understanding of how stars and galaxies formed during the first 5 billion years after the Big Bang has been revolutionized by observations that leverage gra…
NuSTAR Discovery of Dead Quasar Engine in Arp 187
Kohei Ichikawa, Taiki Kawamuro, Megumi Shidatsu +7
Recent active galactic nucleus (AGN) and quasar surveys have revealed a population showing rapid AGN luminosity variability by a factor of . Here we present the most drasti…
Tau lepton asymmetry by sterile neutrino emission -- Moving beyond one-zone supernova models
Anna M. Suliga, Irene Tamborra, Meng-Ru Wu
The mixing of active neutrinos with their sterile counterparts with keV mass is known to have a potentially major impact on the energy loss from the supernova core. By relying on a…
Chandra Spectral and Timing Analysis of Sgr A*'s Brightest X-ray Flares
Daryl Haggard, Melania Nynka, Brayden Mon +17
We analyze the two brightest Chandra X-ray flares detected from Sagittarius A*, with peak luminosities more than 600 x and 245 x greater than the quiescent X-ray emission. The brig…
ALMA Observations of the Terahertz Spectrum of Sagittarius A*
Geoffrey C. Bower, Jason Dexter, Keiichi Asada +11
We present ALMA observations at 233, 678, and 870 GHz of the Galactic Center black hole, Sagittarius A*. These observations reveal a flat spectrum over this frequency range with sp…
Multimessenger Asteroseismology of Core-Collapse Supernovae
John Ryan Westernacher-Schneider, Evan O'Connor, Erin O'Sullivan +4
We investigate correlated gravitational wave and neutrino signals from rotating core-collapse supernovae with simulations. Using an improved mode identification procedure based on…
Rapid Particle Acceleration due to Recollimation Shocks and Turbulent Magnetic Fields in Injected Jets with Helical Magnetic Fields
Kenichi Nishikawa, Yosuke Mizuno, Jose L. Gomez +7
One of the key questions in the study of relativistic jets is how magnetic reconnection occurs and whether it can effectively accelerate electrons in the jet. We performed 3D parti…
ALMA Polarimetry of AT2018cow
K. Y. Huang, J. Shimoda, Y. Urata +7
We present the first radio polarimetric observations of a fast-rising blue optical transient, AT2018cow. Two epochs of polarimetry with additional coincident photometry were perfor…
Finding the remnants of the Milky Way's last neutron star mergers
Meng-Ru Wu, Projjwal Banerjee, Brian D. Metzger +6
The discovery of a binary neutron star merger (NSM) through both its gravitational wave and electromagnetic emission has revealed these events to be key sites of r-process nucleosy…
The Type II-Plateau Supernova 2017eaw in NGC 6946 and Its Red Supergiant Progenitor
Schuyler D. Van Dyk, WeiKang Zheng, Justyn R. Maund +31
We present extensive optical photometric and spectroscopic observations, from 4 to 482 days after explosion, of the Type II-plateau (II-P) supernova (SN) 2017eaw in NGC 6946. SN 20…
Gas Dynamics of the Nickel-56 Decay Heating in Pair-Instability Supernovae
Ke-Jung Chen, S. E. Woosley, Daniel J. Whalen
Very massive 140-260 Msun stars can die as highly-energetic pair-instability supernovae (PI SNe) with energies of up to 100 times those of core-collapse SNe that can completely des…
Three-Dimensional Simulations of Magnetar-Powered Superluminous Supernovae
Ke-Jung Chen, S. E. Woosley, Daniel J. Whalen
A rapidly spinning magnetar in a young supernova (SN) can produce a superluminous transient by converting a fraction of its rotational energy into radiation. Here, we present the f…
Active-sterile Neutrino Oscillations in Neutrino-driven Winds: Implications for Nucleosynthesis
Zewei Xiong, Meng-Ru Wu, Yong-Zhong Qian
A protoneutron star produced in a core-collapse supernova (CCSN) drives a wind by its intense neutrino emission. We implement active-sterile neutrino oscillations in a steady-state…
First Detection of Radio Linear Polarization in a Gamma Ray Burst Afterglow
Y. Urata, K. Toma, K. Huang +6
We report the first detection of radio polarization of a GRB afterglow with the first intensive combined use of telescopes in the millimeter and submillimeter ranges for GRB171205A…

E. E. Nokhrina, L. I. Gurvits, V. S. Beskin +3
We propose a new method of estimating a mass of a super massive black hole residing in the center of an active galaxy. The active galaxy M87 offers a convenient test case for the m…
