Dwarf Galaxies in the MATLAS Survey: Hubble Space Telescope Observations of the Globular Cluster Systems of 74 Ultra Diffuse Galaxies
Francine R. Marleau, Pierre-Alain Duc, Melina Poulain +7
Ultra diffuse galaxies, characterized by their low surface brightness and large physical size, constitute a subclass of dwarf galaxies that challenge our current understanding of g…
Atmosphyre: Modelling Atmospheric Chromatic Dispersion for Multi-Object Spectrographs
J. Stephan, R. Sánchez-Janssen
The wavelength dependent refraction of light in the atmosphere causes the chromatic dispersion of a target on the focal plane of an instrument. This is known as atmospheric dispers…
WST -- Widefield Spectroscopic Telescope: Motivation, science drivers and top-level requirements for a new dedicated facility
Roland Bacon, Vincenzo Maineiri, Sofia Randich +37
In this paper, we describe the wide-field spectroscopic survey telescope (WST) project. WST is a 12-metre wide-field spectroscopic survey telescope with simultaneous operation of a…
Euclid: Early Release Observations -- Dwarf galaxies in the Perseus galaxy cluster
F. R. Marleau, J. -C. Cuillandre, M. Cantiello +193
We make use of the unprecedented depth, spatial resolution, and field of view of the Euclid Early Release Observations of the Perseus galaxy cluster to detect and characterise the…
Euclid: Early Release Observations -- Overview of the Perseus cluster and analysis of its luminosity and stellar mass functions
J. -C. Cuillandre, M. Bolzonella, A. Boselli +199
The Euclid ERO programme targeted the Perseus cluster of galaxies, gathering deep data in the central region of the cluster over 0.7 square degree, corresponding to approximately 0…
Euclid: Early Release Observations -- Globular clusters in the Fornax galaxy cluster, from dwarf galaxies to the intracluster field
T. Saifollahi, K. Voggel, A. Lançon +196
We present an analysis of Euclid observations of a 0.5 deg field in the central region of the Fornax galaxy cluster that were acquired during the performance verification phase…
