Gamma-ray observations of MAXI J1820+070 during the 2018 outburst

H. Abe, S. Abe, V. A. Acciari +439

MAXI J1820+070 is a low-mass X-ray binary with a black hole as a compact object. This binary underwent an exceptionally bright X-ray outburst from March to October 2018, showing ev…

The 3-D X-ray Ejecta Structure of Tycho's Supernova Remnant

Matthew J. Millard, Sangwook Park, Toshiki Sato +5

We present our velocity measurements of 59 clumpy, metal-rich ejecta knots in the supernova remnant (SNR) of SN 1572 (Tycho). We use our 450 ks Chandra High Energy Transmission Gra…

Model-based cross-correlation search for gravitational waves from the low-mass X-ray binary Scorpius X-1 in LIGO O3 data

The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1692

We present the results of a model-based search for continuous gravitational waves from the low-mass X-ray binary Scorpius X-1 using LIGO detector data from the third observing run…

Search for dark matter annihilation signals in the H.E.S.S. Inner Galaxy Survey

H. E. S. S. Collaboration, H. Abdalla, F. Aharonian +137

The central region of the Milky Way is one of the foremost locations to look for dark matter (DM) signatures. We report the first results on a search for DM particle annihilation s…

Spatially resolved study of the SS 433/W50 west region with Chandra: X-ray structure and spectral variation of non-thermal emission

Kazuho Kayama, Takaaki Tanaka, Hiroyuki Uchida +6

The X-ray binary SS 433, embedded in the W50 nebula (or supernova remnant W50), shows bipolar jets that are ejected with mildly relativistic velocities, and extend toward the east…

X-ray Studies of the Inverted Ejecta Layers in the Southeast Area of Cassiopeia A

Tomoya Tsuchioka, Toshiki Sato, Shinya Yamada +1

The central strong activities in core-collapse supernovae expect to produce the overturning of the Fe- and Si/O-rich ejecta during the supernova explosion based on multi-dimensiona…

Search for continuous gravitational wave emission from the Milky Way center in O3 LIGO--Virgo data

The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1667

We present a directed search for continuous gravitational wave (CW) signals emitted by spinning neutron stars located in the inner parsecs of the Galactic Center (GC). Compelling e…

Time-resolved hadronic particle acceleration in the recurrent Nova RS Ophiuchi

H. E. S. S. Collaboration, F. Aharonian, F. Ait Benkhali +171

Recurrent Novae are repeating thermonuclear explosions in the outer layers of white dwarfs, due to the accretion of fresh material from a binary companion. The shock generated by e…

Discovery of Stable Titanium at the Northeastern Jet of Cassiopeia A: Need for a Weak Jet Mechanism?

Takuma Ikeda, Yasunobu Uchiyama, Toshiki Sato +3

The origin of the jet-like structures observed in Cassiopeia A is still unclear, although it seems to be related to its explosion mechanism. X-ray observations of the characteristi…

Evidence for gamma-ray emission from the remnant of Kepler's supernova based on deep H.E.S.S. observations

H. E. S. S. Collaboration, F. Aharonian, F. Ait Benkhali +157

Observations with imaging atmospheric Cherenkov telescopes (IACTs) have enhanced our knowledge of nearby supernova (SN) remnants with ages younger than 500 years by establishing Ca…
