We investigate line formation of Raman-scattered He II at 4851 in an expanding neutral spherical shell that surrounds a point-like He II source located at the center. A new grid-ba…
Localizing the -ray emitting region in the blazar TXS 2013+370
E. Traianou, T. P. Krichbaum, B. Boccardi +9
The -ray production mechanism and its localization in blazars are still a matter of debate. The main goal of this paper is to constrain the location of the high-energy emission…
Chemical properties of two dense cores in a Planck Galactic Cold Clump G168.72-15.48

To deepen our understanding of the chemical properties of the Planck Galactic Cold Clump (PGCC) G168.72-15.48, we performed observations of nine molecular species, namely, \ce{c-C3…
The Gas Accretion History of Low Mass Halos within the Cosmic Web from Cosmological Simulations
Kyungwon Chun, Rory Smith, Jihye Shin +2
Using high resolution hydrodynamical cosmological simulations, we study the gas accretion history of low mass halos located in a field-like, low density environment. We track their…
Gamma-ray Burst Afterglows: Time-Varying Extinction, Polarization, and Colors due to Rotational Disruption of Dust Grains
Thiem Hoang, Nguyen Chau Giang, Le Ngoc Tram
Prompt optical emission of gamma-ray bursts (GRBs) is known to have important effects on the surrounding environment. In this paper, we study rotational disruption and alignment of…
The East Asian Observatory SCUBA--2 survey of the COSMOS field: unveiling 1147 bright sub-millimeter sources across 2.6 square degrees

We present sensitive 850m imaging of the COSMOS field using 640hr of new and archival observations taken with SCUBA-2 at the East Asian Observatory's James Clerk Maxwell Telesco…
Detection of Pristine Circumstellar Material of the Cassiopeia A Supernova
Bon-Chul Koo, Hyun-Jeong Kim, Heeyoung Oh +4
Cassiopeia A is a nearby young supernova remnant that provides a unique laboratory for the study of core-collapse supernova explosions. Cassiopeia A is known to be a Type IIb super…
KMT-2019-BLG-0842Lb: A Cold Planet Below the Uranus/Sun Mass Ratio
Youn Kil Jung, Andrzej Udalski, Weicheng Zang +59
We report the discovery of a cold planet with a very low planet/host mass ratio of , which is similar to the ratio of Uranus/Sun ($q=4.37 \times 10^…
SCUBA-2 Ultra Deep Imaging Eao Survey (Studies) III: Multi-wavelength properties, luminosity functions and preliminary source catalog of 450-m-selected galaxies
Chen-Fatt Lim, Wei-Hao Wang, Ian Smail +35
We construct a SCUBA-2 450-m map in the COSMOS field that covers an area of 300 arcmin and reaches a 1 noise level of 0.65 mJy in the deepest region. We extract 256 sou…
