A Third Epoch Proper Motion Study of The Forward Shock in Kepler's Supernova Remnant
Sadie C. Coffin, Brian J. Williams, Satoru Katsuda
We present measurements of the expansion of Kepler's Supernova Remnant (SNR) over three epochs of Chandra X-ray observations from 2000, 2006, and 2014. As the remnant of a historic…
Observation of Variations in Cosmic Ray Single Count Rates During Thunderstorms and Implications for Large-Scale Electric Field Changes
R. U. Abbasi, T. Abu-Zayyad, M. Allen +160
We present the first observation by the Telescope Array Surface Detector (TASD) of the effect of thunderstorms on the development of cosmic ray single count rate intensity over a 7…
Discovery of the Fastest Early Optical Emission from Overluminous SN Ia 2020hvf: A Thermonuclear Explosion within a Dense Circumstellar Environment
Ji-an Jiang, Keiichi Maeda, Miho Kawabata +28
In this Letter we report a discovery of a prominent flash of a peculiar overluminous Type Ia supernova, SN 2020hvf, in about 5 hours of the supernova explosion by the first wide-fi…
Possible Detection of X-Ray Emitting Circumstellar Material in the Synchrotron-Dominated Supernova Remnant RX J 1713.7-3946
Dai Tateishi, Satoru Katsuda, Yukikatsu Terada +4
We report on a discovery of an X-ray emitting circumstellar material knot inside the synchrotron dominant supernova remnant (SNR) RX J1713.7-3946. This knot was previously thought…
J-GEM optical and near-infrared follow-up of gravitational wave events during LIGO's and Virgo's third observing run
Mahito Sasada, Yousuke Utsumi, Ryosuke Itoh +68
The Laser Interferometer Gravitational-wave Observatory Scientific Collaboration and Virgo Collaboration (LVC) sent out 56 gravitational-wave (GW) notices during the third observin…
Spatially Resolved RGS Analysis of Kepler's Supernova Remnant
Tomoaki Kasuga, Jacco Vink, Satoru Katsuda +4
The distribution and kinematics of the circumstellar medium (CSM) around a supernova remnant (SNR) tell us useful information about the explosion of its natal supernova (SN). Keple…
X-ray Quasi-Periodic Eruptions from two previously quiescent galaxies
R. Arcodia, A. Merloni, K. Nandra +21
Quasi-Periodic Eruptions (QPEs) are extreme high-amplitude bursts of X-ray radiation recurring every few hours and originating near the central supermassive black holes in galactic…
TXS 1206+549: a new -ray detected narrow-line Seyfert 1 galaxy at redshift 1.34?
Suvendu Rakshit, Malte Schramm, C. S. Stalin +5
Radio and -ray loud narrow-line Seyfert 1 galaxies (NLS1s) are unique objects to study the formation and evolution of relativistic jets, as they are believed to have high accret…
AT 2019avd: A novel addition to the diverse population of nuclear transients
A. Malyali, A. Rau, A. Merloni +29
We report on SRG/eROSITA, ZTF, ASAS-SN, Las Cumbres, NEOWISE-R, and Swift XRT/UVOT observations of the unique ongoing event AT 2019avd, located in the nucleus of a previously inact…
