An excessively massive thick disc of the enormous edge-on lenticular galaxy NGC 7572 [PDF]
Monthly notices of the Royal Astronomical Society, 2019 Galactic discs are known to have a complex multilayer structure. An in-depth study of the stellar population properties of the thin and thick components can elucidate the formation and evolution of disc galaxies. Even though thick discs are ubiquitous,

X-ray cavities in the hot corona of the lenticular galaxy NGC 4477 [PDF]
Monthly notices of the Royal Astronomical Society, 2018 NGC 4477 is a low-mass lenticular galaxy in the Virgo Cluster, residing at 100\,kpc to the north of M87. Using a total of 116\,ks {\sl Chandra} observations, we study the interplay between its hot ($\sim$0.3\,keV) gas halo and the central supermassive ...

One Piece at a Time—Adding to the Puzzle of S0 Formation
Galaxies, 2017 Understanding the origin of galaxies remains a topic of debate in the current astronomy. In this work, we have focused on lenticular (S0) galaxies located in low-density environments, using their associated globular cluster (GC) systems as a tool ...

WISDOM Project - III. Molecular gas measurement of the supermassive black hole mass in the barred lenticular galaxy NGC4429 [PDF]
, 2017 As part of the mm-Wave Interferometric Survey of Dark Object Masses project we present an estimate of the mass of the supermassive black hole (SMBH) in the nearby fast-rotating early-type galaxy NGC4429, that is barred and has a boxy/peanut-shaped bulge.

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.

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 ...

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 Study of Nebular Emission on Nearby Spiral Galaxies in the IFU Era
Advances in Astronomy, Volume 2013, Issue 1, 2013., 2013 A new generation of wide‐field emission‐line surveys based on integral field units (IFU) is allowing us to obtain spatially resolved information of the gas‐phase emission in nearby late‐type galaxies, based on large samples of HII regions and full two‐dimensional coverage.

Implications and Applications of Kinematic Galaxy Scaling Relations
International 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 ...
