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…
On the general nature of 21cm-Lyman- emitters cross-correlations during reionisation
Anne Hutter, Caroline Heneka, Pratika Dayal +4
We explore how the characteristics of the cross-correlation functions between the 21cm emission from the spin-flip transition of neutral hydrogen (HI) and early Lyman- (Ly) r…
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…
