Star-forming Rings in Lenticular Galaxies: Origin of the Gas [PDF]
Astronomical Journal, 2019 Rings in S0s are enigmatic features that can, however, betray the evolutionary paths of particular galaxies. We have undertaken long-slit spectroscopy of five lenticular galaxies with UV-bright outer rings.

Chromodynamical analysis of lenticular galaxies using globular clusters and planetary nebulae [PDF]
Monthly notices of the Royal Astronomical Society, 2018 Recovering the origins of lenticular galaxies can shed light on the understanding of galaxy formation and evolution, since they present properties that can be found in both elliptical and spiral galaxies.

Early-type galaxy speciation: Elliptical (E) and ellicular (ES) galaxies in the Mbh-M⋆, sph diagram, and a merger-driven explanation for the origin of ES galaxies, anti-truncated stellar discs in lenticular (S0) galaxies, and the Sérsicification of E galaxy light profiles [PDF]
Monthly notices of the Royal Astronomical SocietyIn a recent series of papers, supermassive black holes were used to discern pathways in galaxy evolution. By considering the black holes’ coupling with their host galaxy’s bulge/spheroid, the progression of mass within each component has shed light on ...

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

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).

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.

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 ...

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.

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 ...
