Tomography of the Ie-Re and L-Sigma Planes
Universe, 2021 We have analyzed the distribution of early-type galaxies (ETGs) in the effective surface intensity vs. effective radius (Ie−Re) plane and in the total luminosity vs. central stellar velocity dispersion (L−σ) diagram, with the aim of studying the physical

Field/isolated lenticular galaxies with high SN values: the case of NGC 4546 and its globular cluster system [PDF]
, 2020 We present a photometric study of the field lenticular galaxy NGC 4546 using Gemini/GMOS imaging in g′r′i′z′. We perform a 2D image decomposition of the surface brightness distribution of the galaxy using galfit, finding that four components adequately ...

The SLUGGS Survey: Understanding Lenticular Galaxy Formation via Extended Stellar Kinematics
Galaxies, 2017 We present the latest published and preliminary results from the SLUGGS Survey discussing the formation of lenticular galaxies through analysis of their kinematics.

Star formation histories of dwarf lenticular galaxies [PDF]
Monthly notices of the Royal Astronomical SocietyStar formation histories (SFHs) are essential for understanding galaxy formation and evolution. We present the mean SFHs of 148 dwarf lenticular galaxies (dS0s) derived from the Sloan Digital Sky Survey (SDSS) spectra.

Lack of FIBRILLIN6 in Arabidopsis thaliana affects light acclimation and sulfate metabolism
New Phytologist, Volume 225, Issue 4, Page 1715-1731, February 2020., 2020 Summary Arabidopsis thaliana contains 13 fibrillins (FBNs), which are all localized to chloroplasts. FBN1 and FBN2 are involved in photoprotection of photosystem II, and FBN4 and FBN5 are thought to be involved in plastoquinone transport and biosynthesis, respectively. The functions of the other FBNs remain largely unknown.

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 ...

Forming Lenticular Galaxies via Violent Disk Instability [PDF]
Astrophysical Journal, 2018 Lenticular galaxies are generally thought to have descended from spirals via morphological transformation, although recent numerical simulations have shown that minor or even major mergers can also lead to an S0-like remnant.

Phenomenological approach to the modelling of elliptical galaxies: The problem of the mass-to-light ratio [PDF]
Serbian Astronomical Journal, 2007 In this paper the problem of the phenomenological modelling of elliptical galaxies using various available observational data is presented. Recently, Tortora, Cardona and Piedipalumbo (2007) suggested a double power law expression for the global ...

The Gas Kinematics, Excitation, and Chemistry, in Connection with Star Formation, in Lenticular Galaxies [PDF]
Astrophysical Journal Supplement Series, 2019 We present long-slit and panoramic spectroscopy of extended gaseous disks in 18 S0 galaxies, mostly in groups. The gas has often decoupled kinematics: at least five galaxies demonstrate strongly inclined large-scale ionized gas disks, seven galaxies ...

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 ...
