Ultraviolet imaging observations of three jellyfish galaxies: Star formation suppression in the centre and ongoing star formation in stripped tails
Koshy George, B. M. Poggianti, Neven Tomičić +13
Spiral galaxies undergo strong ram-pressure effects when they fall into the galaxy cluster potential. As a consequence, their gas is stripped to form extended tails within which st…
Near-infrared characterization of ultra-diffuse galaxies in Abell 2744 by JWST/NIRISS imaging
Ryota Ikeda, Takahiro Morishita, Takafumi Tsukui +10
We present a search and characterization of ultra-diffuse galaxies (UDGs) in the Frontier Fields cluster Abell~2744 at . We use JWST/NIRISS F200W observations, acquired as…
Early Results from GLASS-JWST. XIX: A High Density of Bright Galaxies at in the Abell 2744 Region
Marco Castellano, Adriano Fontana, Tommaso Treu +38
We report the detection of a high density of redshift galaxies behind the foreground cluster Abell 2744, selected from imaging data obtained recently with NIRCam onbo…
VST-GAME: Galaxy Assembly as a function of Mass and Environment with VST. Photometric assessment and density field of MACSJ0416
Nicolas Estrada, Amata Mercurio, Benedetta Vulcani +14
Observational studies have widely demonstrated that galaxy physical properties are strongly affected by the surrounding environment. On one side, gas inflows provide galaxies with…
The production of ionizing photons in UV-faint z~3-7 galaxies
Gonzalo Prieto-Lyon, Victoria Strait, Charlotte A. Mason +20
The demographics of the production and escape of ionizing photons from UV-faint early galaxies is a key unknown in discovering the primary drivers of reionization. With the advent…
Early results from GLASS-JWST. XIV: A spectroscopically confirmed protocluster 650 million years after the Big Bang
Takahiro Morishita, Guido Roberts-Borsani, Tommaso Treu +39
We present the spectroscopic confirmation of a protocluster at behind the galaxy cluster Abell2744 (hereafter A2744-z7p9OD). Using JWST NIRSpec, we find seven galaxies wit…
