Evidence for Mass-dependent Evolution of Transitional Dwarf Galaxies in the Virgo Cluster

The Astrophysical Journal
The presence of transitional dwarf galaxies in cluster environments supports the hypothesis that infalling star-forming galaxies are transformed into quiescent early-type dwarf galaxies (ETdGs) through environmental effects.

Elliptical (E) and ellicular (ES) galaxies in the M_bh-M_*,sph diagram, and a merger-driven explanation for the origin of ES galaxies, anti-truncated stellar discs in lenticular galaxies, and the Sersicification of E galaxy light profiles [PDF]

MNRAS (2024) v.535, p.299
In a recent series of papers, supermassive black holes were used to discern pathways in galaxy evolution. By considering the black holes' coupling with their host galaxy's bulge/spheroid, the progression of mass within each component has shed light on the chronological sequence of galaxy speciation.

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 ...

The Ages and Metallicities of Early Type Galaxies in the Fornax Cluster [PDF]

, 1997
We have measured central line strengths 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. In contrast to the elliptical galaxies in the sample studied by Gonzalez (and recently revisited by Trager) we find that the Fornax ellipticals follow the locus of ...

Bulge-Disk Decomposition of 659 Spiral and Lenticular Galaxy Brightness Profiles [PDF]

, 1998
We present one of the largest homogeneous sets of spiral and lenticular galaxy brightness profile decompositions completed to date. The 659 galaxies in our sample have been fitted with a deVaucouleurs' law for the bulge component and an inner-truncated exponential for the disk component. Of the 659 galaxies in the sample, 620 were successfully fit with

SDSS. IV. MaNGA: The Impact of the Acquisition of Gas with Opposite Angular Momentum on the Evolution of Galaxies

The Astronomical Journal
A gaseous counterrotating galaxy is a galaxy containing a gas component with opposite angular momentum to the main stellar disk. The counterrotating gas provides direct evidence for the accretion of external material, a key aspect in hierarchical galaxy ...

Disk Growth in Bulge-Dominated Galaxies: Molecular Gas and Morphological Evolution

, 2007
Substantial numbers of morphologically regular early-type (elliptical and lenticular) galaxies contain molecular gas, and the quantities of gas are probably sufficient to explain recent estimates of the current level of star formation activity.

Radio Jet Feedback on the Inner Disk of Virgo Spiral Galaxy Messier 58

The Astrophysical Journal
Spitzer spectral maps reveal a disk of highly luminous, warm (>150 K) H _2 in the center of the massive spiral galaxy Messier 58, which hosts a radio-loud active galactic nucleus (AGN). The inner 2.6 kpc of the galaxy appears to be overrun by shocks from

Kinematics And Stellar Population In Isolated Lenticular Galaxies [PDF]

arXiv, 2015
By combining new long-slit spectral data obtained with the Southern African Large Telescope (SALT) for 9 galaxies with previously published our observations for additional 12 galaxies we study the stellar and gaseous kinematics as well as radially resolved stellar population properties and ionized gas metallicity and excitation for a sample of isolated

Current star formation in early-type galaxies and the K+A phenomenon

, 2008
We present the results of an effort to identify and study a sample of the likely progenitors of elliptical (E) and lenticular (S0) K+A galaxies. To achieve this, we have searched a sample ~11,000 nearby (m(r)
