Deep VISTA observations of the Magellanic Clouds (VMCDeep)
M. -R. L. Cioni, A. O. Omkumar, N. J. G. Cross +28
The central regions of galaxies challenge observers with a high density of stars, gas and dust. The LMC hosts a dense stellar bar whereas the SMC hosts a dense core, which have elu…
photoD with Rubin's Data Preview 1: first stellar photometric distances and deficit of faint blue stars. Stellar distances with Rubin's DP1
L. Palaversa, E. Donev, Ž. Ivezić +96
Aims: We investigate the utility of Rubin's Data Preview 1 for estimating stellar number density profile in the Milky Way halo. Methods: Stellar broad-band near-UV to near-IR $ugri…
Strikingly high fraction of fast rotators in Magellanic Cloud star clusters
Greta Ettorre, Alessandro Mazzi, Leo Girardi +14
There has been growing evidence that the rich star clusters in the Magellanic Clouds contain significant fractions of rapidly rotating stars. In this work, we aim to constrain thes…
The Local Ultraviolet to Infrared Treasury II. Refining Star Formation Histories of Ten Metal-Poor Dwarf Galaxies with Simultaneous UV-Optical Two-CMD Fitting
Yumi Choi, Karoline M. Gilbert, Benjamin F. Williams +10
We present the star formation histories (SFHs) of ten metal-poor (<12% Zsun), star-forming dwarf galaxies from the Local Ultraviolet to Infrared Treasury (LUVIT) survey. The derive…
The Local Ultraviolet to Infrared Treasury I. Survey Overview of the Broadband Imaging
Karoline M. Gilbert, Yumi Choi, Martha L. Boyer +21
The Local Ultraviolet to Infrared Treasury (LUVIT) is a Hubble Space Telescope program that combines newly acquired data in the near ultraviolet (NUV), optical, and near infrared (…
Light curve's recovery with Rubin-LSST: II. UnVEiling the darknesS of The gAlactic buLgE (VESTALE) with RR Lyrae
M. Di Criscienzo, S. Leccia, V. Braga +16
This work is part of VESTALE, a project initiated within the Rubin-LSST Cadence Strategy Optimization Process . Its goal is to explore the potential of Rubin-LSST observations aime…
The JWST Resolved Stellar Populations Early Release Science Program VI. Identifying Evolved Stars in Nearby Galaxies
Martha L. Boyer, Giada Pastorelli, Léo Girardi +20
We present an investigation of evolved stars in the nearby star-forming galaxy WLM, using NIRCam imaging from the JWST resolved stellar populations early-release science (ERS) prog…
The JWST Resolved Stellar Populations Early Release Science Program IV: The Star Formation History of the Local Group Galaxy WLM
Kristen. B. W. McQuinn, Max J. B. Newman, Alessandro Savino +23
We present the first star formation history (SFH) and age-metallicity relation (AMR) derived from resolved stellar populations imaged with the JWST NIRCam instrument. The target is…
Dissecting the Gaia HR diagram II. The vertical structure of the star formation history across the Solar Cylinder
Alessandro Mazzi, Léo Girardi, Michele Trabucchi +11
Starting from the Gaia DR3 HR diagram, we derive the star formation history (SFH) as a function of distance from the Galactic Plane within a cylinder centred on the Sun with a 200~…
The first comprehensive Milky Way stellar mock catalogue for the Chinese Space Station Telescope Survey Camera
Yang Chen, Xiaoting Fu, Chao Liu +9
The Chinese Space Station Telescope (CSST) is a cutting-edge two-meter astronomical space telescope currently under construction. Its primary Survey Camera (SC) is designed to cond…
Simulating the Legacy Survey of Space and Time stellar content with TRILEGAL
Piero Dal Tio, Giada Pastorelli, Alessandro Mazzi +19
We describe a large simulation of the stars to be observed by the Vera C. Rubin Observatory Legacy Survey of Space and Time (LSST). The simulation is based on the TRILEGAL code, wh…
The VMC survey -- XLIII. The spatially resolved star formation history across the Large Magellanic Cloud
Alessandro Mazzi, Léo Girardi, Simone Zaggia +19
We derive the spatially-resolved star formation history (SFH) for a deg area across the main body of the Large Magellanic Cloud (LMC), using the near-infrared photometry f…
The VMC survey - XXXI. The spatially resolved star formation history of the main body of the Small Magellanic Cloud
Stefano Rubele, Giada Pastorelli, Leo Girardi +16
We recover the spatially resolved star formation history across the entire main body and Wing of the Small Magellanic Cloud (SMC), using fourteen deep tile images from the VISTA su…
