SCALES. II. The Internal Composition of Giant Star-Forming Clumps at
Boris S. Kalita, Adélaïde Claeyssens, Luis C. Ho +12
Star-forming structures of scale , dubbed 'giant' star-forming clumps, are routinely detected in unlensed surveys of galaxies. Two scenarios are us…
SCALES. I. Bridging Lensed Clump - Giant Clump Scales in Lensed Galaxies at
Boris S. Kalita, Adélaïde Claeyssens, Luis C. Ho +12
Dense star-forming regions in galaxies, often termed 'clumps', have been studied across two distinct regimes of telescope resolution, each motivating interpretations in tensi…
The THESAN-ZOOM project: clumpiness of high-redshift galaxies and its connection to bursty star formation
Zihao Wang, Xuejian Shen, Rahul Kannan +12
Recent JWST observations have revealed diverse high-redshift galaxy morphologies, including a population with irregular and clumpy structures. The physical origin of these structur…
Probing the molecular gas content of galaxies in an over-dense group at z~0.7: A test case for environmental quenching
Jonathan Freundlich, Benoît Epinat, Thierry Contini +14
We investigated the impact of group environment on molecular gas reservoirs at an intermediate redshift by observing the CO(2-1) emission from the galaxy group COSMOS-Gr30 at $z \s…
Halo assembly bias in the early Universe: a clustering probe of the origin of the Little Red Dots
Zihao Wang, Fangzhou Jiang, Haonan Zheng +5
The clustering of galaxies encodes key information about the structure and assembly history of their host dark matter (DM) haloes, providing a powerful probe of the origin of extre…
Controlled Experiments on Dark-Matter Halo Structure and Galaxy Morphology I: What Sets Galaxy Sizes?
Guangze Sun, Fangzhou Jiang, Jing Wang
The properties of galaxies are intricately linked to the characteristics of their host dark-matter haloes. We use a suite of controlled simulations of isolated galaxies to quantify…
Galaxy Metallicity Gradients in the Reionization Epoch from the FIRE-2 Simulations
Xunda Sun, Xin Wang, Fangzhou Jiang +10
We employ the high-redshift suite of FIRE-2 cosmological hydrodynamic zoom-in simulations to investigate the evolution of gas-phase metallicity radial gradients in galaxies in the…
Ultra-diffuse galaxies in the EAGLE simulation
Haonan Zheng, Shihong Liao, Liang Gao +1
We use the highest-resolution EAGLE simulation, Recal-L025N0752, to study the properties and formation of ultra-diffuse galaxies (UDGs). We identify 181 UDGs and find their propert…
Formation and Environmental Context of Giant Bulgeless Disk Galaxies in the Early Universe: Insights from Cosmological Simulations
Fangzhou Jiang, Jinning Liang, Bingcheng Jin +7
Giant bulgeless disk galaxies, theoretically expected to be rare in the early Universe, have been confirmed by the James Webb Space Telescope (JWST) to exist as early as 2 billion…
Massive Black Holes Seeded by Dark Matter -- Implications for Little Red Dots and Gravitational Wave Signatures
Tingwei Shen, Xuejian Shen, Huangyu Xiao +2
Observations of supermassive black holes (SMBHs) at high redshifts challenge standard seeding scenarios. We examine a dissipative self-interacting dark matter (dSIDM) model in whic…
Formation of the Little Red Dots from the Core-collapse of Self-interacting Dark Matter Halos
Fangzhou Jiang, Zixiang Jia, Haonan Zheng +5
We present a statistical study of black hole (BH) formation and growth seeded by gravothermal core collapse of self-interacting dark matter (SIDM) halos at high redshift, using a c…
FEASTS Combined with Interferometry (IV): Mapping HI Emission to a limit of in Seven Edge-on Galaxies
Dong Yang, Jing Wang, Zhijie Qu +17
We present a statistical study of the neutral atomic hydrogen (HI) gas extending into the circumgalactic medium perpendicular to the disk for 7 edge-on galaxies with inclinations a…
Disturbed cold gas in galaxy and structure formation
Siwei Zou, Robert A. Simcoe, Patrick Petitjean +18
Cold and cool gas (T K) in the circumgalactic medium (CGM) and its interaction with galaxies remain poorly understood. Simulations predict that cold gas flows into gala…
FEASTS Combined with Interferometry (II): Significantly Changed HI Surface Densities and Even More Inefficient Star Formation in Galaxy Outer Disks
Jing Wang, Xuchen Lin, Lister Staveley-Smith +12
We update the HI surface density measurements for a subset of 17 THINGS galaxies by dealing with the short-spacing problem of the original VLA HI images. It is the same sample that…
