Outer stellar disks of lenticular galaxies [PDF]
Proceedings of the International Astronomical Union, 2011 AbstractBy studying the radial distribution of the properties of stellar populations in 15 nearby S0 galaxies, I have found that the outer stellar disks are mostly old, with SSP-equivalent ages of 8–15 Gyr, often being older than the bulges. This fact throws doubt on the currently accepted paradigm that S0 galaxies were formed at z=0.4 through the ...

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 ...

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.

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 ...

Footprints in the sand: What can globular clusters tell us about NGC 4753 past? [PDF]
, 2015 NGC 4753 is a bright (M_V approx -22.3) lenticular galaxy. It is a very interesting target to test different theories of formation of lenticular galaxies, due to its low-density environment and complex structure.

An analytical model to kinematically identify thin discs in MaNGA galaxies [PDF]
, 2021 We present an analytical model to identify thin discs in galaxies, and apply this model to a sample of SDSS MaNGA galaxies. This model fits the velocity and velocity dispersion fields of galaxies with regular kinematics. By introducing two parameters $\zeta$ related to the comparison of the model's asymmetric drift correction to the observed gas ...
