Kilonova Emission and Heavy Element Nucleosynthesis
Universe, 2023 The binary neutron star merger observed and localized on 17 August 2017 by the LIGO and Virgo gravitational interferometers and by numerous telescopes on the ground and in orbit linked in an unambiguous way the coalescence of double neutron stars with ...

An excessively massive thick disc of the enormous edge-on lenticular galaxy NGC 7572 [PDF]
Monthly notices of the Royal Astronomical Society, 2019 Galactic discs are known to have a complex multilayer structure. An in-depth study of the stellar population properties of the thin and thick components can elucidate the formation and evolution of disc galaxies. Even though thick discs are ubiquitous,

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
, 2021 This work is a Brazilian-Indian collaboration. It aims at investigating the structuralproperties of Lenticular galaxies in the Stripe 82 using a combination of S-PLUS (Southern Photometric Local Universe Survey) and SDSS data. S-PLUS is a noveloptical multi-wavelength survey which will cover nearly 8000 square degrees of the Southern hemisphere in the ...

Globular Clusters in Lenticular Galaxies: NGC 3115 [PDF]
Symposium - International Astronomical Union, 1988 We present a progress report for the ongoing study of the globular cluster (GC) system around the edge-on lenticular galaxy NGC 3115. This object is one of the best targets for this kind of investigation, due to its proximity (~ 10 Mpc) and favourable inclination (for a deep photometric study and a review of the properties of NGC 3115, see Capaccioli ...

The Structure of Stellar Disks in Isolated Lenticular Galaxies∗ [PDF]
The Astronomical Journal, 2020 Abstract We have obtained imaging data in two photometric bands, g and r, for a sample of 42 isolated lenticular galaxies with the Las Cumbres Observatory 1 m telescope network. We have analyzed the structure of their large-scale stellar disks.

Ages and abundances in large-scale stellar disks of nearby S0 galaxies [PDF]
, 2012 By undertaking deep long-slit spectroscopy with the focal reducer SCORPIO of the Russian 6m telescope, we studied stellar population properties and their variation with radius in 15 nearby S0 galaxies sampling a wide range of luminosities and ...

Early-type galaxy speciation: Elliptical (E) and ellicular (ES) galaxies in the Mbh-M⋆, sph diagram, and a merger-driven explanation for the origin of ES galaxies, anti-truncated stellar discs in lenticular (S0) galaxies, and the Sérsicification of E galaxy light profiles [PDF]
Monthly notices of the Royal Astronomical SocietyIn 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 ...

Lenticular Galaxy Formation: Possible Luminosity Dependence [PDF]
The Astrophysical Journal, 2007 We investigate the correlation between the bulge effective radius (r_e) and disk scale length (r_d), in the near-infrared K band for lenticular galaxies in the field and in clusters. We find markedly different relations between the two parameters as a function of luminosity.
