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

CDM, Feedback and the Hubble Sequence [PDF]
, 2002 We have performed TreeSPH simulations of galaxy formation in a standard LCDM cosmology, including effects of star formation, energetic stellar feedback processes and a meta-galactic UV field, and obtain a mix of disk, lenticular and elliptical galaxies ...

Bose‐Einstein Condensate Dark Matter Halos Confronted with Galactic Rotation Curves
Advances in High Energy Physics, Volume 2017, Issue 1, 2017., 2017 We present a comparative confrontation of both the Bose‐Einstein Condensate (BEC) and the Navarro‐Frenk‐White (NFW) dark halo models with galactic rotation curves. We employ 6 High Surface Brightness (HSB), 6 Low Surface Brightness (LSB), and 7 dwarf galaxies with rotation curves falling into two classes.

Hot Gaseous Halos in Early Type Galaxies
Galaxies, 2017 The hot gas in early type galaxies (ETGs) plays a crucial role in their formation and evolution. As the hot gas is often extended to the outskirts beyond the optical size, the large scale structural features identified by Chandra (including cavities ...

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

Lenticular galaxies in the process of evolution [PDF]
Proceedings of the International Astronomical Union, 2007 AbstractWe present images of a number of lenticular galaxies which appear to be undergoing evolutionary processes such as ram-pressure stripping or gravitational interactions, or possess features indicative of some evolutionary process in the recent past, such as fossil spiral arms, a polar ring-like structure, or a warped disk with box-peanut bulge ...

Radio‐Wave Propagation in Salt Domes: Implications for a UHE Cosmic Neutrino Detector
Advances in High Energy Physics, Volume 2014, Issue 1, 2014., 2014 Salt deposits can be used as a natural dielectric medium for a UHE cosmic neutrino radio detector. Such a detector relies on the capability of reconstructing the initial characteristics of the cosmic neutrino from the measured radio electrical field produced at neutrino’s interaction in salt by the subsequent particle shower.

The Newtonian and MOND dynamical models of NGC 5128: Investigation of the dark matter contribution [PDF]
Serbian Astronomical Journal, 2016 We study the well-known nearby early-type galaxy NGC 5128 (Centaurus A) and use the sample of its globular clusters to analyze its dynamics. We study both Newtonian and MOND models assuming three cases of orbital anisotropies: isotropic case ...

Bar fraction in lenticular galaxies: dependence on luminosity and environment
, 2010 We present a study of bars in lenticular galaxies based on a sample of 371 galaxies from the SDSS-DR 7 and 2MASS in optical and near-infrared bands, respectively.
