The Next Generation Virgo Cluster Survey (NGVS). II. A Catalog of Galaxies in the Virgo Cluster
Laura Ferrarese, Patrick Cote, Lauren A. MacArthur +51
The Next Generation Virgo Cluster Survey (NGVS) is a deep, high resolution imaging campaign that used the 1 deg MegaCam instrument on the Canada-France-Hawaii Telescope to carr…
Very Large Telescope observations of interstellar comet 3I/ATLAS III: High-resolution monitoring of CN and forbidden oxygen emission across the perihelion passage with ESPRESSO
Baltasar Luco, Thomas H. Puzia, Rohan Rahatgaonkar +2
3I/ATLAS is only the third known interstellar object to traverse the Solar System. We obtained high-resolution () spectroscopy of 3I/ATLAS on 23 nights with VLT/ESP…
A Colour-colour Fingerprint Links the UV Upturn in Early-type Galaxies to Second-generation Stars from Dissolved Globular Clusters
Paul Goudfrooij, Andrea Bellini, Thomas M. Brown +1
We address two mass-dependent properties among early-type galaxies (ETGs): (1) abundance ratios [N/Fe] and [Na/Fe], and (2) the centrally concentrated "UV upturn" at far-UV (FUV) w…
Exploring the stellar streams and satellites around the giant low surface brightness galaxy Malin 1
Roy O. E. Bustos-Espinoza, Matias Blaña, Gaspar Galaz +7
Context. Giant Low Surface Brightness galaxies, such as Malin 1, host extended discs exceeding 100 kpc. Their formation and evolution remain debated, with interactions with satelli…
Tidal pre-conditioning and ram-pressure stripping in NGC 1427A. Deep VLT/MUSE spectroscopy and FUV-to-radio observations trace a Fornax Cluster dwarf in transformation
J. P. Carvajal, T. H. Puzia, M. Blaña +11
The early environmental transformation of low-mass cluster galaxies from gas-rich to gas-poor remains poorly constrained, partly because clear, phase-resolved observations are rare…
The complex history of NGC 1427A revealed by its star clusters and star formation history
Katja Fahrion, Michael Hilker, Avinash Chaturvedi +2
Star-forming low-mass galaxies in the dense environments of galaxy clusters provide opportunities to study how environmental effects such as ram-pressure stripping, tidal interacti…
