Low dark matter content of the nearby early-type galaxy NGC 821 [PDF]
Serbian Astronomical Journal, 2014 In this paper we analyze the kinematics and dynamics of the nearby early-type galaxy NGC 821 based on its globular clusters (GCs) and planetary nebulae (PNe).

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 ...

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

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 ...

The Structure of Large-scale Stellar Disks in Cluster Lenticular Galaxies [PDF]
Astronomical Journal, 2018 By obtaining imaging data in two photometric bands for 60 lenticular galaxies—members of eight southern clusters—with the Las Cumbres Observatory one-meter telescope network, we have analyzed the structure of their large-scale stellar disks.

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

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 ...

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.

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.
