An Energetic Consistency Test for Feedback-Driven Gas Loss in Milky Way Dwarf Satellites
Sena A. Matsui, Tsutomu T. Takeuchi, Suchetha Cooray +1
Dwarf spheroidal galaxies (dSphs) contain little detectable cold gas, but the relative roles of stellar feedback, reionization, and environmental effects in their gas loss remain u…
Interaction-induced star formation boosts stellar mass assembly in galaxies
Kiyoaki C. Omori, Marcin Sawicki, Rosa M. Mérida +10
Galaxy interactions are a key ingredient in galaxy evolution; not only are they a primary pathway of galaxy growth and mass assembly, but also a key driver of processes such as sta…
CO Multi-line Imaging of Nearby Galaxies (COMING). XI. Azimuthally averaged star formation rate and stellar mass relation with molecular gas amount
Ayumi Kajikawa, Kazuo Sorai, Kana Morokuma-Matsui +13
This study investigated the relation between the surface density of star formation rate (SFR) (), stellar mass (), and molecular gas mass ($Σ_{M_\ma…
The rise and fall of Little Red Dots could be driven by the environment
Rosa M. Mérida, Gaia Gaspar, Yoshihisa Asada +9
The Little Red Dot (LRD) paradigm comprises three main unknowns that are intrinsically connected: (1) What is the nature of these sources? (2) How do they form? (3) How do they evo…
MINERVA: A NIRCam Medium Band and MIRI Imaging Survey to Unlock the Hidden Gems of the Distant Universe
Adam Muzzin, Katherine A. Suess, Danilo Marchesini +81
We present an overview of the MINERVA survey, a 259.8 hour (prime) and 127 hour (parallel) Cycle 4 treasury program on the James Webb Space Telescope (JWST). MINERVA is obtaining 8…
CANUCS/Technicolor Data Release 1: Imaging, Photometry, Slit Spectroscopy, and Stellar Population Parameters
Ghassan T. E. Sarrouh, Yoshihisa Asada, Nicholas S. Martis +44
We present the first data release of the CAnadian NIRISS Unbiased Cluster Survey (CANUCS), a JWST Cycle 1 GTO program targeting 5 lensing clusters and flanking fields in parallel (…
The connection between galaxy mergers, star formation and AGN activity in the HSC-SSP
Kiyoaki Christopher Omori, Connor Bottrell, Sabine Bellstedt +6
Internal gas inflows driven by galaxy mergers are considered to enhance star formation rates (SFR), fuel supermassive black hole growth and stimulate active galactic nuclei (AGN).…
Environment of SDSS quasars at explored by Subaru HSC
Kohei Shibata, Tohru Nagao, Hisakazu Uchiyama +5
The relationship between quasars and their galaxy environment is important for understanding the evolution of galaxies and supermassive black holes, but it is not fully understood.…
Resolved mass assembly and star formation in Milky Way Progenitors since from JWST/CANUCS: From clumps and mergers to well-ordered disks
Vivian Yun Yan Tan, Adam Muzzin, Ghassan T. E. Sarrouh +17
We present a resolved study of 877 progenitors of Milky Way Analogs (MWAs) at selected with abundance matching in the ten fields of the Canadian NIRISS Unbiased Cluster S…
Katachi: Decoding the Imprints of Past Star Formation on Present Day Morphology in Galaxies with Interpretable CNNs
Juan Pablo Alfonzo, Kartheik G. Iyer, Masayuki Akiyama +8
The physical processes responsible for shaping how galaxies form and quench over time leave imprints on both the spatial (galaxy morphology) and temporal (star formation history; S…
Galaxy mergers in Subaru HSC-SSP: a deep representation learning approach for identification and the role of environment on merger incidence
Kiyoaki Christopher Omori, Connor Bottrell, Mike Walmsley +7
We take a deep learning-based approach for galaxy merger identification in Subaru HSC-SSP, specifically through the use of deep representation learning and fine-tuning, with the ai…
IllustrisTNG in the HSC-SSP: image data release and the major role of mini mergers as drivers of asymmetry and star formation
Connor Bottrell, Hassen M. Yesuf, Gergö Popping +13
At fixed galaxy stellar mass, there is a clear observational connection between structural asymmetry and offset from the star forming main sequence, SFMS. Herein, we use the TNG…
Morphological asymmetries of quasar host galaxies with Subaru Hyper Suprime-Cam
Shenli Tang, John D. Silverman, Hassen M. Yesuf +7
How does the host galaxy morphology influence a central quasar or vice versa? We address this question by measuring the asymmetries of 2424 SDSS quasar hosts at using b…
The bimodality in the mass-metallicity relation in SDSS-MaNGA galaxy pairs
Kiyoaki Christopher Omori, Tsutomu T. Takeuchi
Aims: Interacting galaxies show a metallicity dilution compared to isolated galaxies of similar masses in the mass-metallicity space at the global scale. We investigate the spatial…
Spatially Resolved Properties of Galaxies with a Kinematically Distinct Core
Kiyoaki Christopher Omori, Tsutomu T. Takeuchi
Aims. Interacting galaxies show unique irregularities in their kinematic structure. By investigating the spatially resolved kinematics and stellar population properties of galaxies…
