Forming Lenticular Galaxies via Violent Disk Instability [PDF]

open access: yesThe Astrophysical Journal Letters, 2018
Abstract Lenticular galaxies are generally thought to have descended from spirals via morphological transformation, although recent numerical simulations have shown that minor or even major mergers can also lead to an S0-like remnant. These mechanisms, however, are active in a dense environment such as a group or a cluster of galaxies ...

Implications and Applications of Kinematic Galaxy Scaling Relations

open access: yesInternational Scholarly Research Notices, Volume 2012, Issue 1, 2012., 2012
Galaxy scaling relations, which describe a connection between ostensibly unrelated physical characteristics, testify to an underlying order in galaxy formation that requires understanding. I review the development of a scaling relation that (1) unites the well‐known fundamental plane (FP) relation of giant elliptical galaxies and Tully‐Fisher (TF ...

Local elliptical galaxies: Some aspects of theory vs. observations [PDF]

open access: yesSerbian Astronomical Journal, 2007
In this paper we analyze on, the sample of the local elliptical galaxies, some predictions of various cosmological theories. We start with the sample of ellipticals described in Samurović (2007b) and confront the established concentration parameters and ...

The luminosity function of field galaxies

open access: yes, 2011
Schmidt's method for construction of luminosity function of galaxies is generalized by taking into account the dependence of density of galaxies from the distance in the near Universe.

Dark matter in massive early-type galaxies: 100 years of the jeans equations [PDF]

open access: yesSerbian Astronomical Journal, 2019
In 1919 James Jeans published the book Problems of Cosmogony and Stellar Dynamics in which he summarized his work on dynamics of stellar systems based on his papers published from 1915 onwards.

Mid- to Far-IR Emission and Star Formation in Early-Type Galaxies [PDF]

open access: yes, 2008
Many early-type galaxies have been detected at wavelengths of 24 to 160 micron, but the emission is usually dominated by heating from an AGN or from the evolved stellar population.

Globular Clusters in Lenticular Galaxies: NGC 3115 [PDF]

open access: yesSymposium - 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 APM Bright Galaxy Catalogue [PDF]

open access: yes, 1995
The APM Bright Galaxy Catalogue lists positions, magnitudes, shapes and morphological types for 14,681 galaxies brighter than $b_J$ magnitude 16.44 over a 4,180 square degree area of the southern sky.

STELLAR NUCLEI AND INNER POLAR DISKS IN LENTICULAR GALAXIES [PDF]

open access: yesThe Astronomical Journal, 2016
ABSTRACT I analyze statistics of the stellar population properties for stellar nuclei and bulges of nearby lenticular galaxies in different environments by using panoramic spectral data of the integral-field spectrograph SAURON retrieved from the open archive of the Isaac Newton Group.

Outer Rings in Early-type Galaxies: From Vorontsov-Velyaminov to Present

open access: yesOpen Astronomy, 2014
‘Ringed galaxies’, or disk galaxies with prominent outer ring structures, separated visually from the main galactic bodies, were discovered and intensively studied by B. A. Vorontsov-Vel’yaminov whose 110th anniversary is celebrated this year. We discuss
