Polarized Maser Emission with In-Source Faraday Rotation
Taylor L. Tobin, Malcolm D. Gray, Athol J. Kemball
We discuss studies of polarization in astrophysical masers with particular emphasis on the case where the Zeeman splitting is small compared to the Doppler profile, resulting in a…

Marco Castellano, Adriano Fontana, Tommaso Treu +38
We report the detection of a high density of redshift galaxies behind the foreground cluster Abell 2744, selected from imaging data obtained recently with NIRCam onbo…
A Glimpse of the Stellar Populations and Elemental Abundances of Gravitationally Lensed, Quiescent Galaxies at with Keck Deep Spectroscopy
Zhuyun Zhuang, Nicha Leethochawalit, Evan N. Kirby +13
Gravitational lenses can magnify distant galaxies, allowing us to discover and characterize the stellar populations of intrinsically faint, quiescent galaxies that are otherwise ex…
Supernova 2020wnt: An Atypical Superluminous Supernova with a Hidden Central Engine
Samaporn Tinyanont, Stan E. Woosley, Kirsty Taggart +34
We present observations of a peculiar hydrogen- and helium-poor stripped-envelope (SE) supernova (SN) 2020wnt, primarily in the optical and near-infrared (near-IR). Its peak absolu…
EAVN Astrometry toward the Extreme Outer Galaxy: Kinematic distance with the proper motion of G034.84-00.95
Nobuyuki Sakai, Bo Zhang, Shuangjing Xu +22
We aim to reveal the structure and kinematics of the Outer-Scutum-Centaurus (OSC) arm located on the far side of the Milky Way through very long baseline interferometry (VLBI) astr…
Two decades of optical timing of the shortest-period binary star system HM Cancri
James Munday, T. R. Marsh, Mark Hollands +15
The shortest-period binary star system known to date, RX J0806.3+1527 (HM Cancri), has now been observed in the optical for more than two decades. Although it is thought to be a do…
SN 2022ann: A type Icn supernova from a dwarf galaxy that reveals helium in its circumstellar environment
K. W. Davis, K. Taggart, S. Tinyanont +64
We present optical and near-infrared (NIR) observations of the Type Icn supernova (SN Icn) 2022ann, the fifth member of its newly identified class of SNe. Its early optical spectra…
Early results from GLASS-JWST. XIV: A spectroscopically confirmed protocluster 650 million years after the Big Bang
Takahiro Morishita, Guido Roberts-Borsani, Tommaso Treu +39
We present the spectroscopic confirmation of a protocluster at behind the galaxy cluster Abell2744 (hereafter A2744-z7p9OD). Using JWST NIRSpec, we find seven galaxies wit…
Modelling Cosmic Springs with Finsler and Generalised Finsler Geometries
Matthew J. Lake
We show that the equations of motion governing the dynamics of strings in a compact internal space can be written as dispersion relations, with a local speed that depends on the ve…
The nature of an ultra-faint galaxy in the cosmic Dark Ages seen with JWST
Guido Roberts-Borsani, Tommaso Treu, Wenlei Chen +44
In the first billion years after the Big Bang, sources of ultraviolet (UV) photons are believed to have ionized intergalactic hydrogen, rendering the Universe transparent to UV rad…
Model Independent Approach of the JUNO B Solar Neutrino Program
JUNO Collaboration, Jie Zhao, Baobiao Yue +593
The physics potential of detecting B solar neutrinos will be exploited at the Jiangmen Underground Neutrino Observatory (JUNO), in a model independent manner by using three dis…
The hidden side of cosmic star formation at z > 3: Bridging optically-dark and Lyman break galaxies with GOODS-ALMA
Mengyuan Xiao, David Elbaz, Carlos Gómez-Guijarro +37
Our current understanding of the cosmic star formation history at z>3 is primarily based on UV-selected galaxies (i.e., LBGs). Recent studies of H-dropouts have revealed that we ma…
HD 60431, the CP2 star with the shortest rotational period -- Physical parameters and period analysis
Z. Mikulasek, E. Semenko, E. Paunzen +5
CP2 stars show periodic photometric, spectroscopic, and magnetic variations with the rotational period. They are generally slow rotators, with rotational periods exceeding half a d…
Self-Supervised Clustering on Image-Subtracted Data with Deep-Embedded Self-Organizing Map
Y. -L. Mong, K. Ackley, T. L. Killestein +45
Developing an effective automatic classifier to separate genuine sources from artifacts is essential for transient follow-ups in wide-field optical surveys. The identification of t…
AGN Selection and Demographics in GOODS-S/HUDF from X-ray to Radio
Jianwei Lyu, Stacey Alberts, George H. Rieke +1
We present a comprehensive census of the AGNs in the GOODS-S/HUDF region from the X-ray to the radio, covering both the obscured and unobscured populations. This work includes a ro…
