The GALEX Ultraviolet Atlas of Nearby Galaxies [PDF]

, 2007
We present images, integrated photometry, and surface-brightness and color profiles for a total of 1034 nearby galaxies recently observed by the Galaxy Evolution Explorer (GALEX) satellite in its far-ultraviolet (FUV; λ_(eff) = 1516 Å) and near ...

Exploring Lenticular Galaxy Formation in Field Environments Using NewHorizon: Evidence for Counterrotating Gas Accretion as a Formation Channel

The Astrophysical Journal
The formation pathways of lenticular galaxies (S0s) in field environments remain a matter of debate. We utilize the cosmological hydrodynamic simulation, NewHorizon , to investigate the issue. We select two massive star formation quenched S0s as our main

TDCOSMO

Astronomy & Astrophysics
Spatially resolved stellar kinematics has become a key ingredient in time-delay cosmography to break the mass-sheet degeneracy in the mass profile and in turn provide a precise constraint on the Hubble constant and other cosmological parameters.

Spectroscopic bulge-disc decomposition: a new method to study the evolution of lenticular galaxies

, 2012
A new method for spectroscopic bulge-disc decomposition is presented, in which the spatial light profile in a two-dimensional spectrum is decomposed wavelength-by-wavelength into bulge and disc components, allowing separate one-dimensional spectra for ...

Neutral hydrogen in nearby elliptical and lenticular galaxies: the continuing formation of early-type galaxies

Monthly Notices of the Royal Astronomical Society, 2006
(Abridged) We present deep WSRT observations of neutral hydrogen in 12 nearby elliptical and lenticular galaxies. The selected objects come from a representative sample of nearby galaxies earlier studied at optical wavelengths with the integral-field spectrograph Sauron.

Toward Understanding the Evolutionary Role of Star-forming Lenticular Galaxies: New H i Detections and Comparison with Quiescent S0s and Red Spirals

The Astrophysical Journal
As one type of blue early-type galaxy, the evolutionary history and fate of star-forming lenticular galaxies (S0s) remain elusive. We selected 134 star-forming S0s from the Sloan Digital Sky Survey IV MaNGA survey and found that they have steep and ...

Detection of a Star Forming Galaxy in the Center of a Low-Mass Galaxy Cluster

, 2018
Brightest Cluster Galaxies (BCGs) residing in the centers of galaxy clusters are typically quenched giant ellipticals. A recent study hinted that star-forming galaxies with large disks, so-called superluminous spirals and lenticulars, are the BCGs of a ...

Isolated lenticular galaxies: properties and evolution

, 2014
This work is dedicated to investigation of galaxies that do not fit into a common scenario of galaxy formation - isolated lenticular galaxies. We have studied stellar populations and ionized gas content of a sample of 22 lenticular galaxies (among those 4 targets have appeared to be of erroneous morphological classification) by undertaking deep long ...

Stars throw their weight in old galaxies

, 2012
The observation that old, massive galaxies have a larger fraction of low-mass stars than their younger, lower-mass counterparts adds to mounting evidence that star formation may have been different in the early Universe.Comment: Invited Nature "News and ...

The luminosity function of field galaxies

, 2011
Schmidt's method for construction of luminosity function of galaxies is generalized by taking into account the dependence of density of galaxies from the distance in the near Universe.
