Tomography of the Ie-Re and L-Sigma Planes

open access: yesUniverse, 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

Elliptical galaxies: Rotationally distorted, after all [PDF]

open access: yesSerbian Astronomical Journal, 2009
On the basis of earlier investigations on homeoidally striated Mac Laurin spheroids and Jacobi ellipsoids (Caimmi and Marmo 2005, Caimmi 2006a, 2007), different sequences of configurations are defined and represented in the ellipticity-rotation plane ...

Dense Molecular Gas in Lenticular Galaxies [PDF]

open access: yesPublications of the Astronomical Society of Japan, 2002
We made CO and HCN simultaneous observations of lenticular galaxies (NGC 404, NGC 3593, and NGC 4293) and detected HCN emission in NGC 3593 and NGC 4293 as well as CO in all the galaxies. The $I_\mathrm{HCN} / I_\mathrm{CO}$ ratios were $0.025 \pm 0.006$ and $0.066 \pm 0.005$ in NGC 3593 and NGC 4293, respectively, which are comparable to that of late ...

The SLUGGS Survey: Understanding Lenticular Galaxy Formation via Extended Stellar Kinematics

open access: yesGalaxies, 2017
We present the latest published and preliminary results from the SLUGGS Survey discussing the formation of lenticular galaxies through analysis of their kinematics.

Angular Momentum across the Hubble sequence from the CALIFA survey [PDF]

open access: yes, 2014
We investigate the stellar angular momentum of galaxies across the Hubble sequence from the CALIFA survey. The distribution of CALIFA elliptical and lenticular galaxies in the $\lambda_{\rm Re}-\epsilon_{\rm e}$ diagram is consistent with that shown by ...

Hidden Imprints of Minor Merging in Early-Type Galaxies: Inner Polar Rings and Inclined Large-Scale Gaseous Disks In S0s

open access: yesGalaxies, 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 ...

Lack of FIBRILLIN6 in Arabidopsis thaliana affects light acclimation and sulfate metabolism

open access: yesNew 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.

One Piece at a Time—Adding to the Puzzle of S0 Formation

open access: yesGalaxies, 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 ...

Extremely alpha-Enriched Globular Clusters in Early-Type Galaxies: A Step towards the Dawn of Stellar Populations? [PDF]

open access: yes, 2006
We compare [alpha/Fe], metallicity, and age distributions of globular clusters in elliptical, lenticular, and spiral galaxies, which we derive from Lick line index measurements.

Rotation of the large lenticular galaxy NGC 612* [PDF]

open access: yesMonthly 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 ...
