Abundant Molecular Gas in the Central Region of Lenticular Galaxy PGC 39535

The Astrophysical Journal
Lenticular galaxies (S0s) in the local Universe are generally absent of recent star formation and lack molecular gas. In this paper, we investigate one massive ( M _* ∼ 5 × 10 ^10 M _⊙ ) star-forming S0, PGC 39535, with the Northern Extended Millimeter ...

Different paths, same appearance: An intermediate-age red nugget at z ∼ 0.13 residing in a low-mass group environment

Astronomy & Astrophysics
Massive ultra-compact galaxies are commonly regarded as nearby relics of the compact quiescent population at z ∼ 2–3, and detailed studies have focused so far only on old systems in dense environments.

Galaxy Zoo:dust in spiral galaxies [PDF]

, 2010
We investigate the effect of dust on spiral galaxies by measuring the inclination dependence of optical colours for 24 276 well-resolved Sloan Digital Sky Survey (SDSS) galaxies visually classified via the Galaxy Zoo project.

Euclid: Galaxy morphology and photometry from bulge-disc decomposition of Early Release Observations★

Astronomy & Astrophysics
The background galaxies in Euclid Early Release Observation images of the Perseus cluster make up a remarkable sample for the combination of a 0.57 deg2 area, 25.3 and 23.2 AB mag depth, and angular resolutions in the optical and near-infrared bands of 0⋅

The present-day galaxy population in spiral galaxies [PDF]

, 2009
Although there are many more stellar population studies of elliptical and lenticular galaxies, studies of spiral galaxies are catching up, due to higher signal to noise data on one hand, and better analysis methods on the other.

The mass-dependent interplay of active galacitc nuclei and supernova feedback in shaping the LX–T relation of early-type galaxies

Astronomy & Astrophysics
The observed X-ray luminosity–temperature (LX–T) relation of hot gas in early-type galaxies deviates significantly from the prediction of purely gravitational heating, providing a key constraint on non-gravitational processes such as supernova (SN) and ...

The molecular cloud content of early type galaxies [PDF]

, 1990
A survey of the CO content of early type galaxies led to 24 new detections, mostly lenticular galaxies. The galaxies, which are situated in both the Northern and Southern Hemispheres, were selected as being far-IR luminous compared to their blue ...

Misaligned Gas Acquisition as a Formation Pathway of S0 Galaxies

The Astrophysical Journal
We analyze a sample of 753 S0 galaxies from the MPL-10 of Mapping Nearby Galaxies at Apache Point Observatory survey and investigate the gas–star kinematic misalignment and merger remnant fraction in galaxies with different morphological types.
