Structural and dynamical modeling of WINGS clusters [PDF]

Astronomy & Astrophysics, 2019
The orbital shapes of galaxies of different classes are a probe of their formation and evolution. The Bayesian MAMPOSSt mass-orbit modeling algorithm is used to jointly fit the distribution of elliptical, spiral-irregular, and lenticular galaxies in projected phase space, on three pseudo-clusters (built by stacking the clusters after re-normalizing ...

The Dynamical Distinction between Elliptical and Lenticular Galaxies in Distant Clusters: Further Evidence for the Recent Origin of S0 Galaxies [PDF]

The Astrophysical Journal, 2007
We examine resolved spectroscopic data obtained with the Keck II telescope for 44 spheroidal galaxies in the fields of two rich clusters, Cl0024+16 (z=0.40) and MS0451-03 (z=0.54), and contrast this with similar data for 23 galaxies within the redshift interval 0 ...

The Invisibility of Scotomas I: The Carving Hypothesis

Optometry and Vision Science, Volume 100, Issue 8, Page 515-529, August 2023., 2023
SIGNIFICANCE Veridical depictions of scene appearance with scotomas allow better understanding of the impact of field loss and may improve the development and implementation of rehabilitation. Explanation and depiction of the invisibility of scotoma may lead to patients' understanding and thus better compliance with related treatments.

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 ...

The present-day galaxy population in spiral galaxies [PDF]

, 2009
Although there are many more stellar population studies of elliptical and lenticular galaxies, studies of spiral galaxies are catching up, due to higher signal to noise data on one hand, and better analysis methods on the other.

The central velocity dispersion in elliptical and lenticular galaxies as an extragalactic distance indicator

The Astrophysical Journal, 1982
The Faber-Jackson relation between absolute magnitude M/sub T//sup 0/ and central velocity dispersion sigma/sub upsilon/ is reexamined for a sample of 157 normal, noninteracting galaxies, 82 ellipticals (T = -5, -4), and 75 lenticulars (T = -3, -2, -1). The values of sigma/sub upsilon/ are weighted means from various sources reduced to a uniform system

Chromodynamical analysis of lenticular galaxies using globular clusters and planetary nebulae [PDF]

, 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.

Extended stellar kinematics of elliptical galaxies in the Fornax cluster?;?? [PDF]

, 1998
. We present extended stellar kinematics for a sample of elliptical galaxies in the Fornax cluster. Out of the 13 galaxies presented here, ve (FCC 119, FCC 136, NGC 1373, NGC 1428, FCC 335) have no pre-viously published kinematical data.

Extended ionized gas in elliptical galaxies

, 1998
For the last ten years faint ionized gas detection has been carried out for elliptical galaxies with success. The kinematics is essential to understand galaxy gas origin and fate. Here we present a sample of 11 elliptical and lenticular galaxies observed
