Formation of a Massive Lenticular Galaxy Under the Tidal Interaction with a Group of Dwarf Galaxies
The Astrophysical Journal Letters, 2023 Based on the atomic-hydrogen (H i ) observations using the Five-hundred-meter Aperture Spherical radio Telescope, we present a detailed study of the gas-rich massive S0 galaxy NGC 1023 in a nearby galaxy group.

Creating lenticular galaxies with mergers [PDF]
Proceedings of the International Astronomical Union, 2016 AbstractLenticular galaxies (S0s) represent the majority of early-type galaxies in the local Universe, but their formation channels are still poorly understood. While galaxy mergers are obvious pathways to suppress star formation and increase bulge sizes, the marked parallelism between spiral and lenticular galaxies (e.g.

The SLUGGS survey: chromodynamical modelling of the lenticular galaxy NGC 1023 [PDF]
Monthly Notices of the Royal Astronomical Society, 2015 Globular clusters (GCs) can be considered discrete, long-lived, dynamical tracers that retain crucial information about the assembly history of their parent galaxy. In this paper, we present a new catalogue of GC velocities and colours for the lenticular galaxy NGC 1023, we study their kinematics and spatial distribution, in comparison with the ...

Rotation of the large lenticular galaxy NGC 612* [PDF]
Monthly Notices of the Royal Astronomical Society, 1980 The radio galaxy NGC 612 (≡ PKS 0131 – 36) has been studied spectroscopically and the velocity field measured in emission lines of [O II], [O III] and Hα. A rotation curve has been determined to a radius of 40 kpc (H=50kms−1Mpc−1). The rotation curve of this SO galaxy is essentially flat, as is found for many late-type systems, with an amplitude of ...

S-PLUS: LEnticular Galaxies in Stripe 82 (LEGS82) [PDF]
Anais da Academia Brasileira de Ciências, 2021 This work is a Brazilian-Indian collaboration. It aims at investigating the structural properties of Lenticular galaxies in the Stripe 82 using a combination of S-PLUS (Southern Photometric Local Universe Survey) and SDSS data.

PGC 44685: A Dwarf Star-forming Lenticular Galaxy with a Wolf–Rayet Population [PDF]
The Astrophysical JournalLenticular galaxies (S0s) are formed mainly from the gas stripping of spirals in the cluster. But how S0s form and evolve in the field is still in need of being resolved.

Exploring Lenticular Galaxy Formation in Field Environments Using NewHorizon: Evidence for Counterrotating Gas Accretion as a Formation Channel [PDF]
The Astrophysical JournalThe 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

Thick Disks of Lenticular Galaxies [PDF]
Astronomy & Astrophysics, 2004 Thick disks are faint and extended stellar components found around several disk galaxies including our Milky Way. The Milky Way thick disk, the only one studied in detail, contains mostly old disk stars (~10 Gyr), so that thick disks are likely to trace the early stages of disk evolution.
