A slow bar in the lenticular barred galaxy NGC 4277 [PDF]
, 2022 Aims. We characterised the properties of the bar hosted in lenticular galaxy NGC 4277, which is located behind the Virgo cluster. Methods. We measured the bar length and strength from the surface photometry obtained from the broad-band imaging of the ...

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 ...

Outer disks of lenticular galaxies [PDF]
Proceedings of the International Astronomical Union, 2011 By studying the stellar population properties along the radius in 15 nearby S0 galaxies, I have found that the outer stellar disks are mostly old, with the SSP-equivalent ages of 8-15 Gyr, being often older than the bulges. This fact puts into doubt a currently accepted paradigm that S0 galaxies have formed at z=0.4 by quenching star formation in ...

Investigation of the Fundamental Plane Relationship For the Evolution of the Elliptical and Lenticular Galaxies [PDF]
مجلة التربية والعلمThe Fundamental Plane relates the effective radius and surface brightness of an early-type galaxy to its velocity dispersion. It is important in understanding galaxy formation and evolution processes. The present work aims to investigate this relation as

Properties of stellar populations in isolated lenticular galaxies [PDF]
Astrophysical Bulletin, 2014 In this paper we present the results of long-slit spectral observations for a sample of isolated lenticular galaxies, made with the SCORPIO and SCORPIO-2 spectrographs of the 6-meter BTA telescope of the SAO RAS. By applying full spectral fitting technique using the stellar population evolutionary synthesis models, we have measured the radial profiles ...

Galaxies, 2015 I discuss my latest observational data and ideas about decoupled gaseous subsystems in nearby lenticular galaxies. As an extreme case of inclined gaseous disks, I demonstrate a sample of inner polar disks, derive their incidence, about 10% among the ...

The level of photometry is the basic level of the Hungarian galaxy [PDF]
مجلة التربية والعلم, 2007 The photometric and fundamental plane for a sample of early type galaxies(elliptical and lenticular galaxies) which belongs to Virgo cluster have been calculated by fitting the Sersic model ( r1/n-model) to the surface brightness profiles along the major

Journal of Geophysical Research: Planets, Volume 125, Issue 12, December 2020., 2020 Abstract This paper provides an overview of the Curiosity rover's exploration at Vera Rubin ridge (VRR) and summarizes the science results. VRR is a distinct geomorphic feature on lower Aeolis Mons (informally known as Mount Sharp) that was identified in orbital data based on its distinct texture, topographic expression, and association with a hematite

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 ...
