X-ray Properties of Young Early Type Galaxies: II. Abundance Ratio in the Hot ISM

, 2012
Using Chandra X-ray observations of young, post-merger elliptical galaxies, we present X-ray characteristics of age-related observational results, by comparing with typical old elliptical galaxies in terms of metal abundances in the hot interstellar ...

Are disk galaxies the progenitors of giant ellipticals? [PDF]

, 2007
A popular formation scenario for giant elliptical galaxies proposes that they might have formed from binary mergers of disk galaxies. Difficulties with the scenario that emerged from earlier studies included providing the necessary stellar mass and ...

Equilibrium Figures inside the Dark-Matter Ring and the Shapes of Elliptical Galaxies

Open Astronomy, 2015
We solve the general problem of the theory of equilibrium figures and analyze two classes of liquid rotating gravitating figures residing inside a gravitating ring or torus.

Cosmicflows-4

The Astrophysical Journal, 2023
With Cosmicflows- 4, distances are compiled for 55,877 galaxies gathered into 38,065 groups. Eight methodologies are employed, with the largest numbers coming from the correlations between the photometric and kinematic properties of spiral galaxies (TF ...

Alignment of galaxies relative to their local environment in SDSS-DR8

, 2016
We study the alignment of galaxies relative to their local environment in SDSS-DR8 and, using these data, we discuss evolution scenarios for different types of galaxies. We defined a vector field of the direction of anisotropy of the local environment of

Chandra observation of the central galaxies in A1060 cluster of galaxies [PDF]

, 2002
Chandra observation of the central region of the A1060 cluster of galaxies resolved X-ray emission from two giant elliptical galaxies, NGC 3311 and NGC 3309. The emission from these galaxies consists of two components, namely the hot interstellar medium (

Resolving the Extended Stellar Halos of Nearby Galaxies: The Wide-Field PISCeS Survey

Galaxies, 2017
The wide-field Panoramic Imaging Survey of Centaurus and Sculptor (PISCeS) investigates the resolved stellar halos of two nearby galaxies (the spiral NGC 253 and the elliptical Centaurus A, D ∼ 4 Mpc) out to a galactocentric radius of 150 kpc ...

Influence of major mergers on the radio emission of elliptical galaxies

, 2012
We investigate the influence of major mergers on the radio emission of elliptical galaxies. We use a complete sample of close pairs, which contains 475 merging and 1828 non-merging paired elliptical galaxies of ...

Spectral Energy Distribution Mapping of Two Elliptical Galaxies on sub-kpc scales [PDF]

, 2016
We use high-resolution Herschel-PACS data of 2 nearby elliptical galaxies, IC1459 & NGC2768 to characterize their dust and stellar content. IC1459 & NGC2768 have an unusually large amount of dust for elliptical galaxies (1-3 x 10^5 Msun), this dust is ...
