The radio continuum structure of bright galaxies at 1.4 GHZ. [PDF]

, 1980
The (double) source structure of the radio continuum emission of the more powerful radio sources associated with galaxies is only briefly discussed in Chapter VI. In Chapter VII we gave a fractional luminosity function for these sources. Some evidence is

7. Galaxies

, 2016
‘Galaxies’ describes galaxy morphology, the chemical evolution of galaxies, and stellar dynamics. A galaxy consists of a huge number of point masses—stars and dark matter—that move freely in the gravitational field that they jointly generate.

The HST/ACS Coma Cluster Survey: VI. Colour gradients in giant and dwarf early-type galaxies [PDF]

, 2011
Using deep, high-spatial-resolution imaging from the Hubble Space Telescope/Advanced Camera for Surveys (HST/ACS) Coma Cluster Treasury Survey, we determine colour profiles of early-type galaxies in the Coma cluster.

The galaxy morphology-density relation in the EAGLE simulation

, 2023
The optical morphology of galaxies is strongly related to galactic environment, with the fraction of early-type galaxies increasing with local galaxy density.

The time delay between star formation quenching and morphological transformation of galaxies in clusters: a phase–space view of EDisCS [PDF]

, 2019
We explore the possible effect of cluster environments on the structure and star formation histories of galaxies by analysing the projected phase–space (PPS) of intermediate-redshift clusters (0.4 z 0.8).

The Surface Brightness Fluctuations and Globular Cluster Populations of Virgo Elliptical and Lenticular Galaxies

, 1999
The Virgo cluster of galaxies is a complex system composed of several subclusters or "clouds." Although the relative positions of clouds can be determined by the low precision measurement of many galaxies in each cloud, the internal structure ...

SDSS-IV MaNGA:Variation of the Stellar Initial Mass Function in Spiral and Early-type Galaxies [PDF]

, 2017
We perform Jeans anisotropic modeling (JAM) on elliptical and spiral galaxies from the MaNGA DR13 sample. By comparing the stellar mass-to-light ratios estimated from stellar population synthesis and from JAM, we find a systematic variation of the ...

Lenticular galaxies - the one in the middle

, 2016
The lenticular (S0) galaxies introduced by Hubble (1936) as a morphological transition class between elliptical and early-type spiral galaxies, which have the most massive bulges among disk galaxies, may have formed in several different ways as suggested

Transforming gas-rich low-mass disky galaxies into ultra-diffuse galaxies by ram pressure

, 2021
International audienceFaint extended elliptically shaped ultra-diffuse galaxies and slightly brighter and more compact dwarf elliptical and lenticular stellar systems are common in galaxy clusters.

The morphology of galaxies in the Baryon Oscillation Spectroscopic Survey

, 2011
We study the morphology and size of the luminous and massive galaxies at 0.3 z Hubble Space Telescope (HST) imaging, and catalogues, from the COSMic Origins Survey (COSMOS).
