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.

The Origin of Star-forming Rings in S0 Galaxies

The Astrophysical Journal, 2023
Spatially resolved integral field spectroscopic maps in a sample of 532 S0 galaxies from the MaNGA survey have unveiled the existence of inner rings (〈 R 〉 ∼ 1 R _e ) betraying ongoing star formation in a number of these objects.

Luminosities of Barred and Unbarred S0 Galaxies

, 2012
Lenticular galaxies with M_B < -21.5 are almost exclusively unbarred, whereas both barred and unbarred objects occur at fainter luminosity levels. This effect is observed both for objects classified in blue light, and for those that were classified in ...

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 Baryonic Halos of Isolated Elliptical Galaxies

Galaxies, 2017
Without the interference of a number of events, galaxies may suffer in crowded environments (e.g., stripping, harassment, strangulation); isolated elliptical galaxies provide a control sample for the study of galaxy formation.

What Are S0 Galaxies?

, 2009
The data collected in the Shapley-Ames catalog of bright galaxies show that lenticular (S0) galaxies are typically about a magnitude fainter than both elliptical (E) and early spiral (Sa) galaxies.

The APM Bright Galaxy Catalogue [PDF]

, 1995
The APM Bright Galaxy Catalogue lists positions, magnitudes, shapes and morphological types for 14,681 galaxies brighter than $b_J$ magnitude 16.44 over a 4,180 square degree area of the southern sky.

The luminosity function of field galaxies

, 2011
Schmidt's method for construction of luminosity function of galaxies is generalized by taking into account the dependence of density of galaxies from the distance in the near Universe.

Outer Rings in Early-type Galaxies: From Vorontsov-Velyaminov to Present

Open Astronomy, 2014
‘Ringed galaxies’, or disk galaxies with prominent outer ring structures, separated visually from the main galactic bodies, were discovered and intensively studied by B. A. Vorontsov-Vel’yaminov whose 110th anniversary is celebrated this year. We discuss

Globular clusters and planetary nebulae kinematics and X-ray emission in the early-type galaxy NGC 5128 [PDF]

Serbian Astronomical Journal, 2006
The estimates of the mass of the galaxy NGC 5128 based on the different mass tracers, globular clusters (GCs) and planetary nebulae (PNe), are presented.
