The impact of an evolving stellar initial mass function on early galaxies and reionisation
Elie Rasmussen Cueto, Anne Hutter, Pratika Dayal +5
Observations with JWST have revealed an unexpected high abundance of bright z>10 galaxy candidates. We explore whether a stellar initial mass function (IMF) that becomes increasing…
MAGNIF: A Tentative Lensed Rotating Disk at detected by JWST NIRCam WFSS with Dynamical Forward Modeling
Zihao Li, Zheng Cai, Fengwu Sun +39
We report galaxy MACS0416-Y3 behind the lensing cluster MACSJ0416.1--2403 as a tentative rotating disk at detected through its [OIII] emission in JWST NIRCam…
Low-redshift Lyman Continuum Survey: Radio continuum properties of low- Lyman continuum emitters
Omkar Bait, Sanchayeeta Borthakur, Daniel Schaerer +20
Sources that leak Lyman-continuum (LyC) photons and lead to the reionisation of the universe are intensely studied using multiple observing facilities. Recently, the Low-redshift L…
The COSMOS-Web ring: in-depth characterization of an Einstein ring lensing system at z~2
W. Mercier, M. Shuntov, R. Gavazzi +34
Aims. We provide an in-depth analysis of the COSMOS-Web ring, an Einstein ring at z=2 that we serendipitously discovered in the COSMOS-Web survey and possibly the most distant lens…
Simulating the diversity of shapes of the Lyman- line
Jeremy Blaizot, Thibault Garel, Anne Verhamme +6
The Ly line is a powerful probe of distant galaxies, which contains information about inflowing/outflowing gas through which Ly photons scatter. To develop our understanding…
"Dust Giant": Extended and Clumpy Star-Formation in a Massive Dusty Galaxy at
Vasily Kokorev, Shuowen Jin, Carlos Gómez-Guijarro +8
We present NOEMA CO (2-1) line and ALMA 870 m continuum observations of a main-sequence galaxy at . The galaxy was initially selected as a "gas-giant", based on the gas…
A SPectroscopic survey of biased halos In the Reionization Era (ASPIRE): JWST Reveals a Filamentary Structure around a z=6.61 Quasar
Feige Wang, Jinyi Yang, Joseph F. Hennawi +56
We present the first results from the JWST ASPIRE program (A SPectroscopic survey of biased halos In the Reionization Era). This program represents an imaging and spectroscopic sur…
A SPectroscopic survey of biased halos In the Reionization Era (ASPIRE): A First Look at the Rest-frame Optical Spectra of Quasars Using JWST
Jinyi Yang, Feige Wang, Xiaohui Fan +53
Studies of rest-frame optical emission in quasars at have historically been limited by the wavelengths accessible by ground-based telescopes. The James Webb Space Telescope (…
A Bayesian approach to the halo galaxy - supermassive black hole connection through cosmic time
Christopher Boettner, Maxime Trebitsch, Pratika Dayal
We study the co-evolution of dark matter halos, galaxies and supermassive black holes using an empirical galaxy evolution model from -- . We demonstrate that by connectin…
Insight Into a Lensed -dark Galaxy and its Quiescent Companion at
Vasily Kokorev, Shuowen Jin, Georgios E. Magdis +13
Using the novel /NIRCam observations in the Abell 2744 field, we present a first spatially resolved overview of an -dark galaxy, spectroscopically confirmed at …
