JWST Reveals a Population of Ultrared, Flattened Galaxies at 2 ≲ z ≲ 6 Previously Missed by HST
The Astrophysical Journal Letters, 2023 With just a month of data, JWST is already transforming our view of the universe, revealing and resolving starlight in unprecedented populations of galaxies.

Observations of Lenticular Galaxies at the 6-m Telescope of the Special Astrophysical Observatory [PDF]
GROUND-BASED ASTRONOMY IN RUSSIA. 21ST CENTURY. Proceedings of the All-Russian Conference, 2020 This is a historical review covering the last 30 years of the observational study of lenticular galaxies at the 6m telescope BTA of the Special Astrophysical Observatory of the Russian Academy of Sciences.

Elliptical galaxies: Rotationally distorted, after all [PDF]
Serbian Astronomical Journal, 2009 On the basis of earlier investigations on homeoidally striated Mac Laurin spheroids and Jacobi ellipsoids (Caimmi and Marmo 2005, Caimmi 2006a, 2007), different sequences of configurations are defined and represented in the ellipticity-rotation plane ...

Clustercentric Distance or Local Density? It Depends on Galaxy Morphology
The Astrophysical Journal, 2023 Determining which between projected local density and distance from the cluster center plays a major role in regulating morphological fractions in clusters is a longstanding debate.

Outer disks of lenticular galaxies [PDF]
Proceedings of the International Astronomical Union, 2011 By studying the stellar population properties along the radius in 15 nearby S0 galaxies, I have found that the outer stellar disks are mostly old, with the SSP-equivalent ages of 8-15 Gyr, being often older than the bulges. This fact puts into doubt a currently accepted paradigm that S0 galaxies have formed at z=0.4 by quenching star formation in ...

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

Dense Molecular Gas in Lenticular Galaxies [PDF]
Publications of the Astronomical Society of Japan, 2002 We made CO and HCN simultaneous observations of lenticular galaxies (NGC 404, NGC 3593, and NGC 4293) and detected HCN emission in NGC 3593 and NGC 4293 as well as CO in all the galaxies. The $I_\mathrm{HCN} / I_\mathrm{CO}$ ratios were $0.025 \pm 0.006$ and $0.066 \pm 0.005$ in NGC 3593 and NGC 4293, respectively, which are comparable to that of late ...

Star-forming Rings in Lenticular Galaxies: Origin of the Gas [PDF]
Astronomical Journal, 2019 Rings in S0s are enigmatic features that can, however, betray the evolutionary paths of particular galaxies. We have undertaken long-slit spectroscopy of five lenticular galaxies with UV-bright outer rings.

Field/isolated lenticular galaxies with high SN values: the case of NGC 4546 and its globular cluster system [PDF]
, 2020 We present a photometric study of the field lenticular galaxy NGC 4546 using Gemini/GMOS imaging in g′r′i′z′. We perform a 2D image decomposition of the surface brightness distribution of the galaxy using galfit, finding that four components adequately ...
