Context. Observations of neutral hydrogen (H I) and molecular gas show that 50% of all nearby early-type galaxies contain some cold gas. Molecular gas is always found in small gas discs in the central region of the galaxy, while neutral hydrogen is often distributed in a low-column density disc or ring typically extending well beyond the stellar body. Dust is frequently found in early-type galaxies as well. Aims. The goal of our study is to understand the link between dust and cold gas in… 
Census and classification of low-surface-brightness structures in nearby early-type galaxies from the MATLAS survey
The morphology of galaxies gives essential constraints on the models of galaxy evolution. The morphology of the features in the low-surface-brightness regions of galaxies has not been fully explored
Inverted metallicity gradients in two Virgo cluster star-forming dwarf galaxies: evidence of recent merging?
We present integral field spectroscopy observations of two star-forming dwarf galaxies in the Virgo cluster (VCC135 and VCC324) obtained with PMAS/PPak at the Calar Alto 3.5 meter telescope. We
Ubiquitous signs of interactions in early-type galaxies with prolate rotation
Context. A small fraction of early-type galaxies (ETGs) show prolate rotation; that is, they rotate around their long photometric axis. In simulations, certain configurations of galaxy mergers are
Insights into the Evolution of Five Isolated Galaxies
Galaxy evolution is believed to be conditioned by the environment. Isolated galaxies or galaxies in poor groups are an excellent laboratory to study evolutionary mechanisms where effects of the
Atomic hydrogen clues to the formation of counterrotating stellar discs
We present interferometric HI observations of six double-disc stellar counterrotator ("2$\sigma$") galaxies from the Atlas3D sample. Three are detected in HI emission; two of these are new
Machine learning technique for morphological classification of galaxies from the SDSS
Context. Machine learning methods are effective tools in astronomical tasks for classifying objects by their individual features. One of the promising utilities is related to the morphological
A deep learning approach to test the small-scale galaxy morphology and its relationship with star formation activity in hydrodynamical simulations
Hydrodynamical simulations of galaxy formation and evolution attempt to fully model the physics that shapes galaxies. The agreement between the morphology of simulated and real galaxies, and the


Neutral hydrogen in nearby elliptical and lenticular galaxies: the continuing formation of early-type galaxies
We present the results of deep Westerbork Synthesis Radio Telescope observations of neutral hydrogen in 12 nearby elliptical and lenticular galaxi es. The selected objects come from a representative
Star formation associated with neutral hydrogen in the outskirts of early-type galaxies
About 20 per cent of all nearby early-type galaxies (M⋆≳ 6 × 109 M⊙) outside the Virgocluster are surrounded by a disc or ring of low-column-density neutralhydrogen (H I) gas with typical radii of
Extended, regular HI structures around early-type galaxies
Abstract: We discuss the morphology and kinematics of the HI of a sample of 30 southern gas-rich early-type galaxies selected from the HI Parkes All-Sky Survey (HIPASS). This is the largest
Spatial Distribution of Warm Dust in Early-Type Galaxies
Images taken with the Infrared Array Camera on the Spitzer Space Telescope show that the spatial distribution of warm dust emission in lenticular galaxies is often organized into dynamically stable
Molecular gas and star formation in early-type galaxies
We present new mm interferometric and optical integral-field unit (IFU) observations and construct a sample of 12 elliptical (E) and lenticular (S0) galaxies with molecular gas which have both CO and
The dust properties of all early-type galaxies imaged with the Planetary Camera of the Hubble Space Telescope in cycles I-III are examined. Dust is detected in 31 out of 64 galaxies, although the
Dust properties in the cold and hot gas phases of the ATLAS3D early-type galaxies as revealed by AKARI
Context. The properties of the dust in the cold and hot gas phases of early-type galaxies (ETGs) are key to understanding ETG evolution. Aims. We aim to conduct a systematic study of the dust in a
Galaxy Zoo: dust and molecular gas in early-type galaxies with prominent dust lanes
We explore the properties of dust and associated molecular gas in 352 nearby (0.01 < z < 0.07) early-type galaxies (ETGs) with prominent dust lanes, drawn from the Sloan Digital Sky Survey (SDSS).
We have conducted an archival Spitzer study of 38 early-type galaxies in order to determine the origin of the dust in approximately half of this population. Our sample galaxies generally have good
The SAMI galaxy survey: Kinematics of dusty early-type galaxies
Recently, large samples of visually classified early-type galaxies (ETGs) containing dust have been identified using space-based infrared observations with the Herschel Space Telescope. The presence
