Abundant Molecular Gas in the Central Region of Lenticular Galaxy PGC 39535 [PDF]
The Astrophysical JournalLenticular 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 ...

Luminosities of Barred and Unbarred S0 Galaxies [PDF]
, 2012 Lenticular galaxies with M_B < -21.5 are almost exclusively unbarred, whereas both barred and unbarred objects occur at fainter luminosity levels. This effect is observed both for objects classified in blue light, and for those that were classified in ...

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.299In 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.

A slow bar in the lenticular barred galaxy NGC 4277 [PDF]
Astronomy & Astrophysics, 2022 Aims.We characterised the properties of the bar hosted in lenticular galaxy NGC 4277, which is located behind the Virgo cluster.Methods.We measured the bar length and strength from the surface photometry obtained from the broad-band imaging of the Sloan Digital Sky Survey and we derived the bar pattern speed from the stellar kinematics obtained from ...

Inner structure of the lenticular galaxy NGC 3384 [PDF]
Monthly Notices of the Royal Astronomical Society, 1984 La region interne de la galaxie lenticulaire NGC 3384 presente une structure complexe. La haute resolution (FWHM≃0,7 arc sec) obtenue pour cette etude photometrique permet de montrer que la faible structure allongee croisant le bulbe perpendiculairement a l'axe principal de la galaxie n'est probablement pas une barre, mais un petit anneau polaire de ...

The low dark matter content of the lenticular galaxy NGC 3998 [PDF]
, 2016 We observed the lenticular galaxy NGC 3998 with the Mitchell Integral-Field Spectrograph and extracted line-of-sight velocity distributions out to 3 half-light radii.

Inner Polar Rings in Regular Lenticular Galaxies [PDF]
The Astronomical Journal, 2004 We have investigated a sample of S0 galaxies, mostly with circumnuclear dust lanes orthogonal to their major axes, chosen from Hubble Space Telescope Wide Field Planetary Camera 2 images. Two-dimensional spectroscopy undertaken with the Multipupil Fiber Spectrograph of the 6 m telescope of the Special Astrophysical Observatory of the Russian Academy of

Exponential bulges and antitruncated disks in lenticular galaxies [PDF]
Proceedings of the International Astronomical Union, 2008 The presence of exponential bulges and anti-truncated disks has been noticed in many lenticular galaxies. In fact, it could be expected because the very formation of S0 galaxies includes various processes of secular evolution. We discuss how to distinguish between a pseudobulge and an anti-truncated disk, and also what particular mechanisms may be ...
