A machine learning approach to estimating HI deficiency in galaxies
Filip Janák, Boris Deshev, Roman Nagy +1
Measurements of the HI content of galaxies serve as an important tracer for probing the impact of environment on galaxy evolution. More specifically, the HI deficiency (defined as…
Portrait of a Galaxy on FIRE: Is the -bimodality a natural consequence of inside-out disc growth in a hierarchical formation scenario?
MarÃa Benito, Annaliina Aavik, Giuseppina Battaglia +7
The chemical dichotomy in the [/Fe]-[Fe/H] plane is a consequence of the complex processes underlying the formation and evolution of disc galaxies such as observed in the stell…
High resolution observations of 'dark' neutral hydrogen clouds in the Virgo cluster with the Very Large Array
Robert Minchin, Rhys Taylor, Emmanuel Momjian +2
We have observed six `dark' neutral hydrogen (HI) clouds discovered in the Virgo cluster by the Arecibo Galaxy Environment Survey (AGES) with the Karl G. Jansky Very Large Array (V…
Newborn jet in the symbiotic system R Aquarii
T. Liimets, D. P. K. Banerjee, M. Santander-GarcÃa +12
R Aquarii (R Aqr) is a well-known symbiotic binary that has attracted renewed interest during its recent periastron passage, an event that occurs only once every about 40 years. Th…
The richest clusters in the Coma and Leo superclusters: Properties and evolution
Maret Einasto, Peeter Tenjes, Rain Kipper +6
We study the substructure, connectivity, and galaxy content of galaxy clusters A1656 and 1367 in the Coma supercluster and of A1185 in the Leo supercluster with the aim of understa…
ALMA-JELLY I: High Resolution CO(2-1) Observations of Ongoing Ram Pressure Stripping in NGC 4858 Reveal Asymmetrical Gas Tail Formation and Fallback
Harrison J. Souchereau, Jeffrey D. P. Kenney, Pavel Jachym +13
We present new CO(2-1) observations (resolution pc) of the Coma cluster jellyfish galaxy NGC 4858 obtained from the ALMA-JELLY large program. Analyzing this data alon…
