Searching for EeV photons with Telescope Array Surface Detector and neural networks
Telescope Array Collaboration, R. U. Abbasi, T. Abu-Zayyad +126
Ultra-high-energy photons play an important role in probing astrophysical models and beyond-Standard-Model scenarios. We report updated limits on the diffuse photon flux using Tele…
Morphology and Mach Number Distribution of Merger Shock Surfaces in Merging Galaxy Clusters
Eunyu Lee, Dongsu Ryu, Hyesung Kang
In a binary merger of two subclusters with comparable masses, a pair of merger shocks are typically generated, often manifesting as double radio relics. Using cosmological hydrodyn…
Detecting and Characterizing Young Quasars. III. The Impact of Gravitational Lensing Magnification

We test the impact of gravitational lensing on the lifetime estimates of seven high-redshift quasars at redshift . The targeted quasars are identified by their small obs…
Electron-Ion Temperature Ratio in Astrophysical Shocks
John C. Raymond, Parviz Ghavamian, Artem Bohdan +9
Collisionless shock waves in supernova remnants and the solar wind heat electrons less effectively than they heat ions, as is predicted by kinetic simulations. However, the values…

We present 850 m dust polarization observations of the massive DR21 filament from the B-fields In STar-forming Region Observations (BISTRO) survey, using the POL-2 polarimeter a…
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…
The JCMT BISTRO Survey: A Spiral Magnetic Field in a Hub-filament Structure, Monoceros R2
Jihye Hwang, Jongsoo Kim, Kate Pattle +157
We present and analyze observations of polarized dust emission at 850 m towards the central 1 pc 1 pc hub-filament structure of Monoceros R2 (Mon R2). The data are obta…
Searching for Islands of Reionization: A Potential Ionized Bubble Powered by a Spectroscopic Overdensity at z = 8.7
Rebecca L. Larson, Steven L. Finkelstein, Taylor A. Hutchison +10
We present the results from a spectroscopic survey using the MOSFIRE near-infrared spectrograph on the 10m Keck telescope to search for Ly emission from candidate galaxies at z…
The Prevalence of Galaxy Overdensities Around UV-Luminous Lyman Emitters in the Epoch of Reionization
E. Leonova, P. A. Oesch, Y. Qin +19
Before the end of the epoch of reionization, the Hydrogen in the Universe was predominantly neutral. This leads to a strong attenuation of Ly lines of galaxies in th…
Effects of Forcing on Shocks and Energy Dissipation in Interstellar and Intracluster Turbulences
Hyunjin Cho, Dongsu Ryu, Hyesung Kang
Observations indicate that turbulence in the interstellar medium (ISM) is supersonic () and strongly magnetized (), while in the intracluster medium…
H-alpha emission in local galaxies: star formation, time variability and the diffuse ionized gas
Sandro Tacchella, Aaron Smith, Rahul Kannan +6
The nebular recombination line H is widely used as a star-formation rate (SFR) indicator in the local and high-redshift Universe. We present a detailed H radiative transfer s…
VERA astrometry toward the Perseus arm gap
Nobuyuki Sakai, Hiroyuki Nakanishi, Kohei Kurahara +4
The Perseus arm has a gap in Galactic longitudes (l) between 50 and 80 deg (hereafter the Perseus arm gap) where the arm has little star formation activity. To better understand th…
On the Stellar Populations of Galaxies at z=9-11: The Growth of Metals and Stellar Mass at Early Times
Sandro Tacchella, Steven L. Finkelstein, Micaela Bagley +18
We present a detailed stellar population analysis of 11 bright () galaxies at (three spectroscopically confirmed) to constrain the chemical enrichment and growth o…
Evidence from Disrupted Halo Dwarfs that -process Enrichment via Neutron Star Mergers is Delayed by Myrs
Rohan P. Naidu, Alexander P. Ji, Charlie Conroy +10
The astrophysical origins of -process elements remain elusive. Neutron star mergers (NSMs) and special classes of core-collapse supernovae (rCCSNe) are leading candidates. Due t…
(Re)Solving Reionization with Lyα: How Bright Lyα Emitters account for the Cosmic Ionizing Background
Jorryt Matthee, Rohan P. Naidu, Gabriele Pezzulli +12
The cosmic ionizing emissivity from star-forming galaxies has long been anchored to UV luminosity functions. Here we introduce an emissivity framework based on Ly emitters (LAEs…
