High-Redshift Galaxy Candidates at z > 6 as Revealed by JWST Observations of MACS0647
Keduse Worku, Tiger Yu-Yang Hsiao, Dan Coe +9
We present a catalog of 57 high-redshift galaxy candidates, including 14 spectroscopic confirmations ( -- 9.25), 2 Little Red Dots (, 5.81), and 2 interlo…
Little red dot variability over a century reveals black hole envelope via a giant Einstein cross
Zijian Zhang, Mingyu Li, Masamune Oguri +79
"Little red dots" (LRDs) represent a new population of astronomical objects uncovered by JWST whose nature remains debated. Although many LRDs are suspected as active galactic nucl…
The stellar and dark matter distributions in early-type galaxies measured by stacked weak gravitational lensing
Momoka Fujikawa, Masamune Oguri
We investigate stellar mass and central dark matter density profiles of photometric luminous red galaxies with stellar masses of using weak gravitation…
ALMA Lensing Cluster Survey: Molecular Gas Properties of Line-Emitting Galaxies from a Blind Survey
Kanako Narita, Bunyo Hatsukade, Seiji Fujimoto +16
We present results of a blind search for line-emitting galaxies using ALMA Lensing Cluster Survey data. We detected seven line emitters, one of which is [C\,{\sc ii}] at $z = 6.071…
VENUS: A Strongly Lensed Clumpy Galaxy at behind the Galaxy Cluster MACS J0257.1-2325
Minami Nakane, Vasily Kokorev, Seiji Fujimoto +75
We present the discovery of a strongly lensed galaxy at , dubbed the ``Misty Moons'', identified in the JWST Treasury Survey, Vast Exploration for Nascent, Unexplored S…
The Hubble constant from the improved lens modeling of cluster-lensed supernova Refsdal with new spectroscopic redshifts and the Jackknife method
Yuting Liu, Masamune Oguri
Time-delay cosmology offers an alternative approach to measuring the Hubble constant (), which is distinct from the cosmic distance ladder and cosmic microwave background radi…
Constraining the lensing dispersion from the angular clustering of binary black hole mergers
Fumihiro Chuman, Masamune Oguri
Gravitational waves from inspiraling compact binaries provide direct measurements of luminosity distances and serve as a powerful probe of the high-redshift Universe. In addition t…
Dust-obscured Galaxies with Broken Power-law Spectral Energy Distributions Discovered by UNIONS
Taketo Yoshida, Tohru Nagao, Yoshiki Toba +11
We report on the spectral energy distributions (SEDs) of infrared-bright dust-obscured galaxies (DOGs) with . Using photometry from the deep and wide…
The Jackknife method as a new approach to validate strong lens mass models
Shun Nishida, Masamune Oguri, Yoshinobu Fudamoto +1
The accuracy of a mass model in the strong lensing analysis is crucial for unbiased predictions of physical quantities such as magnifications and time delays. While the mass model…
ALMA Observations of [OI]145um and [NII]205um Emission lines from Star-Forming Galaxies at
Yoshinobu Fudamoto, Akio K. Inoue, Rychard Bouwens +21
We present results of new observations of [OI]145um and [NII]205um emission lines from four star-forming galaxies at redshifts between and that have previous detect…
Medium-band Astrophysics with the Grism of NIRCam In Frontier fields (MAGNIF): Spectroscopic Census of H Luminosity Functions and Cosmic Star Formation at and 6.3
Shuqi Fu, Fengwu Sun, Linhua Jiang +35
We measure H luminosity functions (LFs) at redshifts and 6.3 using the JWST MAGNIF (Medium-band Astrophysics with the Grism of NIRCam In Frontier fields) survey. MA…
A stellar dynamical mass measurement of an inactive black hole at redshift 2
Andrew B. Newman, Meng Gu, Sirio Belli +34
Supermassive black holes and their host galaxies grow together over time, producing correlations between the black hole mass and various galaxy properties. Determining the evolutio…

Rates of Strongly Lensed Tidal Disruption Events
E. Mamuzic, T. Ryu, S. H. Suyu +4
In the coming years, surveys such as the Rubin Observatory's Legacy Survey of Space and Time (LSST) are expected to increase the number of observed Tidal Disruption Events (TDEs) s…
