Satellites of Satellites: The Case for Carina and Fornax

Autor: Facundo A. Gómez, Federico Marinacci, Rüdiger Pakmor, Robert J. J. Grand, Stephen A. Pardy, Volker Springel, Christine M. Simpson, Julio F. Navarro, Elena D'Onghia

We use the Auriga cosmological simulations of Milky Way (MW)-mass galaxies and their surroundings to study the satellite populations of dwarf galaxies in $��$CDM. As expected from prior work, the number of satellites above a fixed stellar mass is

Chemo-Dynamical Clustering applied to APOGEE data: Re-Discovering Globular Clusters

Autor: Bret Hanlon, Elena D'Onghia, Eva K. Grebel, Boquan Chen, Anna Pasquali, Stephen A. Pardy, Clio Bertelli Motta

We have developed a novel technique based on a clustering algorithm which searches for kinematically- and chemically-clustered stars in the APOGEE DR12 Cannon data. As compared to classical chemical tagging, the kinematic information included in our

Models of Tidally Induced Gas Filaments in the Magellanic Stream

Publikováno v: The Astrophysical Journal. 857:101

The Magellanic Stream and Leading Arm of HI that stretches from the Large and Small Magellanic Clouds (LMC and SMC) and over 200 degrees of the Southern sky is thought to be formed from multiple encounters between the LMC and SMC. In this scenario, m

We use mid-infrared 3.6 and 4.5microns imaging of NGC 3906 from the Spitzer Survey of Stellar Structure in Galaxies (S4G) to understand the nature of an unusual offset between its stellar bar and the photometric center of an otherwise regular, circul

ALFALFA Discovery of the Nearby Gas-rich Dwarf Galaxy Leo P. V. Neutral Gas Dynamics and Kinematics

Autor: Evan D. Skillman, Edward C. Elson, John M. Cannon, Katherine L. Rhode, Steven R. Warren, Elizabeth A. K. Adams, Jayaram Chengular, John J. Salzer, Martha P. Haynes, Alberto D. Bolatto, Kristen B. W. McQuinn, Riccardo Giovanelli, Stephen A. Pardy, Elijah Z. Bernstein-Cooper

We present new HI spectral line imaging of the extremely metal-poor, star-forming dwarf irregular galaxy Leo P. Our HI images probe the global neutral gas properties and the local conditions of the interstellar medium (ISM). The HI morphology is slig
