Galactic bars are already mature at Cosmic Noon: bar strength and flatness at z ~ 1.5
Boris S. Kalita, Luis C. Ho, John D. Silverman +6
In this work, we explore the nature of galactic bars. Once thought to be highly transient, our results demonstrate otherwise. Our sample consists of nine massive ($>10^{10.5}…
The role of environment on the evolution of disc galaxies density profiles New insights from simulations and comparison to Euclid data
M. Mondelin, F. Bournaud, J-C. Cuillandre +1
Galactic discs are known to have exponential radial profiles in luminosity and stellar surface density in their bright inner regions. Nonetheless, their faint outer regions often d…
Euclid: Early Release Observations -- The surface brightness and colour profiles of the far outskirts of galaxies in the Perseus cluster
M. Mondelin, F. Bournaud, J. -C. Cuillandre +110
The Perseus field captured by Euclid as part of its Early Release Observations provides a unique opportunity to study cluster environment ranging from outskirts to dense regions. L…
On the origin of compressive turbulence in protoclumps in high redshift disks
Omry Ginzburg, Avishai Dekel, Nir Mandelker +4
The giant, star forming clumps in gas-rich, high redshift disks are commonly assumed to form due to gravitational instabilities, in which protoclumps have a Toomre- parameter le…
Pearls on a string: Dark and bright galaxies on a strikingly straight and narrow filament
Maryam Arabsalmani, Sambit Roychowdhury, Benjamin Schneider +11
We identify a chain of galaxies along an almost straight line in the nearby Universe with a projected length of ~5 Mpc. The galaxies are distributed within projected distances of o…
