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.

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.

Properties of the Photometric Components of Lenticular Galaxies

Advances in Astronomy, Volume 2012, Issue 1, 2012., 2012
After almost one century since their definition, the origin of lenticular galaxies is still a matter of debate. Several formation processes have been proposed in order to explain the wide variety of their observational properties. These properties could indicate that the class of lenticulars is a family formed by galaxies with different formations and ...

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

Monthly notices of the Royal Astronomical Society, 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.

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 evolution of barred galaxies in the EAGLE simulations [PDF]

, 2021
We study the morphologies of 3,964 galaxies and their progenitors with $M_\star>10^{10} M_\odot$ in the reference EAGLE hydrodynamical simulation from redshifts $z=1$ to $z=0$, concentrating on the redshift evolution of the bar fraction.

DISKY ELLIPTICAL GALAXIES AND THE ALLEGEDLY OVER-MASSIVE BLACK HOLE IN THE COMPACT MASSIVE “ES” GALAXY NGC 1271 [PDF]

, 2016
While spiral and lenticular galaxies have large-scale disks extending beyond their bulges, and most local early-type galaxies with 1010 < M*/M⊙ < 2 × 1011 contain a disk (e.g., ATLAS3D), the early-type galaxies do possess a range of disk sizes.

VEGAS-SSS. A VST survey of elliptical galaxies in the southern hemisphere: analysis of small stellar systems. Testing the methodology on the globular cluster system in NGC3115 [PDF]

, 2014
We present a study of globular clusters (GCs) and other small stellar systems (SSSs) in the field of NGC3115, observed as part of the VEGAS imaging survey, carried out with the VST telescope. We use deep g and i data of NGC3115, a well-studied lenticular

CENTRAL STELLAR MASS DEFICITS IN THE BULGES OF LOCAL LENTICULAR GALAXIES, AND THE CONNECTION WITH COMPACT z ∼ 1.5 GALAXIES [PDF]

, 2013
We have used the full radial extent of images from the Hubble Space Telescope's Advanced Camera for Surveys and Wide Field Planetary Camera 2 to extract surface brightness profiles from a sample of six, local lenticular galaxy candidates. We have modeled

Repainting the colour-mass diagrams by unearthing the green mountain: dust-rich S0 galaxies in the colour-(galaxy stellar mass) diagram, and the colour-(black hole mass) relations for dust-poor versus dust-rich galaxies [PDF]

Monthly notices of the Royal Astronomical Society
Lenticular galaxies are notoriously misclassified as elliptical galaxies and, as such, a (disc inclination)-dependent correction for dust is often not applied to the magnitudes of dusty lenticular galaxies.
