A ∼50,000 m⊙ solar mass black hole in the nucleus of rgg 118
TL;DR: In this article, the authors presented optical and X-ray observations of the dwarf galaxy RGG 118 taken with the Magellan Echellette Spectrograph on the 6.5 m Clay Telescope and Chandra Xray Observatory.
Journal ArticleDOI
The Romulus cosmological simulations: a physical approach to the formation, dynamics and accretion models of SMBHs
Michael Tremmel,Michael D. Karcher,Fabio Governato,Marta Volonteri,Thomas R. Quinn,Andrew Pontzen,Lauren Anderson,Jillian Bellovary +7 more
TL;DR: In this paper, the authors present a novel implementation of supermassive black hole (SMBH) formation, dynamics and accretion in the massively parallel tree+SPH code, CHANGA.
Journal ArticleDOI
Observational evidence for intermediate-mass black holes
TL;DR: Intermediate-mass black holes (IMBHs), with masses in the range 100-106M⊙, are the link between stellar-mass BHs and supermassive BHS (SMBHs) as mentioned in this paper.
Journal ArticleDOI
Nuclear star clusters
TL;DR: A review of the current knowledge about nuclear star clusters (NSCs), the spectacularly dense and massive assemblies of stars found at the centers of most galaxies, can be found in this paper.
Journal ArticleDOI
A New Sample of (Wandering) Massive Black Holes in Dwarf Galaxies from High-resolution Radio Observations
TL;DR: In this article, the authors presented a sample of nearby dwarf galaxies with radio-selected accreting massive black holes (BHs), the majority of which are non-nuclear.

TL;DR: The Two Micron All Sky Survey (2MASS) as mentioned in this paper collected 25.4 Tbytes of raw imaging data from two dedicated 1.3 m diameter telescopes located at Mount Hopkins, Arizona and CerroTololo, Chile.
Journal ArticleDOI
On the variation of the initial mass function
TL;DR: In this paper, the uncertainty inherent in any observational estimate of the IMF is investigated by studying the scatter introduced by Poisson noise and the dynamical evolution of star clusters, and it is found that this apparent scatter reproduces quite well the observed scatter in power-law index determinations, thus defining the fundamental limit within which any true variation becomes undetectable.
Journal ArticleDOI
Measuring Reddening with Sloan Digital Sky Survey Stellar Spectra and Recalibrating SFD
TL;DR: In this paper, the authors measured the difference between the measured and predicted colors of a star, as derived from stellar parameters from the Sloan Extension for Galactic Understanding and Exploration Stellar Parameter Pipeline, and achieved uncertainties of 56, 34, 25, and 29 mmag in the colors u − g, g − r, r − i, and i − z, per star.

Astrophysics of Gaseous Nebulae and Active Galactic Nuclei
TL;DR: In this paper, a comparison of theory with observations internal dynamics of gaseous nebulae interstellar dust H II regions in the galactic context is presented. But the results are limited to the case of active galactic nuclei.

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.
