Resequencing the Hubble sequence and the quadratic (black hole mass)-(spheroid stellar mass) relation for elliptical galaxies [PDF]

, 2023
One of the most protracted problems in astronomy has been understanding the evolution of galaxy morphology. Much discussion has surrounded how lenticular galaxies may form a bridging population between elliptical and spiral galaxies.

Tomography of the Ie-Re and L-Sigma Planes

Universe, 2021
We have analyzed the distribution of early-type galaxies (ETGs) in the effective surface intensity vs. effective radius (Ie−Re) plane and in the total luminosity vs. central stellar velocity dispersion (L−σ) diagram, with the aim of studying the physical

Lenticular galaxy formation: possible luminosity dependence [PDF]

, 2007
We investigate the correlation between the bulge effective radius (re ) and disk scale length (rd ) in the near-infrared K band for lenticular galaxies in the field and in clusters.

One Piece at a Time—Adding to the Puzzle of S0 Formation

Galaxies, 2017
Understanding the origin of galaxies remains a topic of debate in the current astronomy. In this work, we have focused on lenticular (S0) galaxies located in low-density environments, using their associated globular cluster (GC) systems as a tool ...

The assembly histories of lenticular galaxies from their large radii kinematic profiles

, 2022
The thesis provides a contribution to understanding the nature of lenticular galaxies in low-density environments from the analysis of the stellar, globular cluster and planetary nebulae kinematics reaching out to the outskirts of the galaxies, which are

A Virgo Environmental Survey Tracing Ionised Gas Emission (VESTIGE): XII. Ionised gas emission in the inner regions of lenticular galaxies [PDF]

, 2022
International audienceAs part of the Virgo Cluster Survey Tracing Ionised Gas Emission, a blind narrow-band Hα+[NII] imaging survey of the Virgo cluster carried out with MegaCam at the CFHT, we discovered eight massive (1010 ≲ Mstar ≲ 1011 M⊙) lenticular

Lenticular galaxies - the one in the middle [PDF]

, 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

Counter-Rotating Disks in Galaxies

, 2023
reservedCounter-rotation is a phenomenon found in some galaxies; it happens when a counter-rotating disk which rotates in an opposite direction to the main disk is found.

Lenticular galaxies and their environments

, 2009
It is widely believed that lenticular (S0) galaxies were initially spirals from which the gas has been removed by interactions with hot cluster gas, or by ram pressure stripping of cool gas from spirals that are orbiting within rich clusters of galaxies.

The star formation history of early-type galaxies in the fornax cluster [PDF]

, 1998
We have measured central line strengths and line-strength gradients for a complete sample of early-type galaxies in the Fornax cluster, comprising 11 elliptical and 11 lenticular galaxies, more luminous than M(_B) = -17.
