The physical properties of z>2 Lyman limit systems: new constraints for feedback and accretion models
Michele Fumagalli, John M. O'Meara, J. Xavier Prochaska
We study the physical properties of a homogeneous sample of 157 optically-thick absorption line systems at redshifts ~1.8-4.4, selected from a high-dispersion spectroscopic survey…
The Cluster-Scale Environment of PKS 2155-304
E. P. Farina, M. Fumagalli, R. Decarli +1
PKS 2155-304 is one of the brightest extragalactic source in the X-ray and EUV bands, and is a prototype for the BL Lac class of objects. In this paper we investigate the large-sca…
MUSE sneaks a peek at extreme ram-pressure stripping events. II. The physical properties of the gas tail of ESO137-001
Matteo Fossati, Michele Fumagalli, Alessandro Boselli +3
We present a study of the physical properties of the disc and tail of ESO137-001, a galaxy suffering from extreme ram-pressure stripping during its infall into the Norma cluster. W…
Star Cluster Properties in Two LEGUS Galaxies Computed with Stochastic Stellar Population Synthesis Models
Mark R. Krumholz, Angela Adamo, Michele Fumagalli +14
We investigate a novel Bayesian analysis method, based on the Stochastically Lighting Up Galaxies (slug) code, to derive the masses, ages, and extinctions of star clusters from int…
The Keck+Magellan Survey for Lyman Limit Absorption III: Sample Definition and Column Density Measurements
J. Xavier Prochaska, John M. O'Meara, Michele Fumagalli +2
We present an absorption-line survey of optically thick gas clouds -- Lyman Limit Systems (LLSs) -- observed at high dispersion with spectrometers on the Keck and Magellan telescop…
Halpha3: an Halpha imaging survey of HI selected galaxies from ALFALFA. V: The Coma Supercluster survey completion
Giuseppe Gavazzi, Guido Consolandi, Elisa Viscardi +8
Neutral hydrogen represents the major observable baryonic constituent of galaxies that fuels the formation of stars through the transformation in molecular hydrogen. The emission o…
SLUG -- Stochastically Lighting Up Galaxies. III: A Suite of Tools for Simulated Photometry, Spectroscopy, and Bayesian Inference with Stochastic Stellar Populations
Mark R. Krumholz, Michele Fumagalli, Robert L. da Silva +2
Stellar population synthesis techniques for predicting the observable light emitted by a stellar population have extensive applications in numerous areas of astronomy. However, acc…
