Coevolution (Or Not) of Supermassive Black Holes and Host Galaxies

TL;DR: In this paper, supermassive black holes (BHs) have been found in 85 galaxies by dynamical modeling of spatially resolved kinematics, and it has been shown that BHs and bulges coevolve by regulating each other's growth.
Journal ArticleDOI

Improving the full spectrum fitting method: accurate convolution with Gauss-Hermite functions

TL;DR: In this article, the authors present an updated summary of the penalized pixel-fitting (pPXF) method, which is used to extract the stellar and gas kinematics, as well as the stellar population of galaxies via full spectrum fitting.

The next generation virgo cluster survey (ngvs). i. introduction to the survey

Laura Ferrarese, +56 more
TL;DR: The Next Generation Virgo Cluster Survey (NGVS) as discussed by the authors uses the 1 deg2 MegaCam instrument on the Canada-France-Hawaii Telescope to carry out a comprehensive optical imaging survey of the Virgo cluster, from its core to its virial radius.

The Seventh Data Release of the Sloan Digital Sky Survey

Kevork N. Abazajian, +223 more
TL;DR: A series of improvements to the spectroscopic reductions are described, including better flat fielding and improved wavelength calibration at the blue end, better processing of objects with extremely strong narrow emission lines, and an improved determination of stellar metallicities.

The Seventh Data Release of the Sloan Digital Sky Survey

TL;DR: SDSS-II as mentioned in this paper is the last data set of the Sloan Digital Sky Survey and contains 357 million distinct objects, including 930,000 galaxies, 120,000 quasars, and 460,000 stars.

Third Reference Catalogue of Bright Galaxies

TL;DR: In this article, a reference catalogue of bright galaxies in three volumes reflects the explosive growth of extragalactic astronomy over the last 15 years and includes all galaxies with apparent diameters larger than one arc minute, magnitudes brighter than about magnitude 15.5, and redshifts not larger than 15,000 km/sec.
Journal ArticleDOI

Parametric Recovery of Line‐of‐Sight Velocity Distributions from Absorption‐Line Spectra of Galaxies via Penalized Likelihood

TL;DR: In this paper, the authors investigate the accuracy of the parametric recovery of the line-of-sight velocity distribution (LOSVD) of the stars in a galaxy while working in pixel space.
