Neutral hydrogen structures trace dust polarization angle: Implications for cosmic microwave background foregrounds
S. E. Clark, J. Colin Hill, J. E. G. Peek +2
Using high-resolution data from the Galactic Arecibo L-Band Feed Array HI (GALFA-HI) survey, we show that linear structure in Galactic neutral hydrogen (HI) correlates with the mag…
The Influence of Environment on the Circumgalactic Medium
Joo Heon Yoon, Mary Putman
The effect of environment on the circumgalactic medium (CGM) is investigated through a comparison of Lya absorption line data in the Virgo Cluster and the field. This Letter uses t…
Choirs, HI Galaxy Groups: Catalogue and Detection of Star-forming Dwarf Group Members
Sarah M. Sweet, Gerhardt Meurer, Michael J. Drinkwater +24
Hα observations centred on galaxies selected from the HI Parkes All Sky Survey (HIPASS, Barnes et al. 2001) typically show one and sometimes two star-forming galaxies within the ap…
Gas Accretion is Dominated by Warm Ionized Gas in Milky Way-Mass Galaxies at z ~ 0
M. Ryan Joung, Mary E. Putman, Greg L. Bryan +2
We perform high-resolution hydrodynamic simulations of a Milky Way-mass galaxy in a fully cosmological setting using the adaptive mesh refinement code, Enzo, and study the kinemati…
Warm Gas in the Virgo Cluster: I. Distribution of Lya Absorbers
Joo Heon Yoon, Mary Putman, Christopher Thom +2
The first systematic study of the warm gas (T=10^4-5 K) distribution across a galaxy cluster is presented using multiple background QSOs to the Virgo Cluster. We detect 25 Lya abso…
A Gaseous Group with Unusual Remote Star Formation
Nitza Santiago-Figueroa, Mary E. Putman, Jessica Werk +2
We present VLA 21-cm observations of the spiral galaxy ESO 481-G017 to determine the nature of remote star formation traced by an HII region found 43 kpc and ~800 km s^-1 from the…
Gas Condensation in the Galactic Halo
M. Ryan Joung, Greg L. Bryan, Mary E. Putman
Using adaptive mesh refinement (AMR) hydrodynamic simulations of vertically stratified hot halo gas, we examine the conditions under which clouds can form and condense out of the h…
Metal Transport to the Gaseous Outskirts of Galaxies
Jessica Werk, Mary Putman, Gerhardt Meurer +1
We present a search for outlying HII regions in the extended gaseous outskirts of nearby (D < 40 Mpc) galaxies, and subsequent multi-slit spectroscopy used to obtain the HII region…
The Metal-Enriched Outer Disk of NGC 2915
Jessica K. Werk, Mary E. Putman, Gerhardt R. Meurer +5
We present optical emission-line spectra for outlying HII regions in the extended neutral gas disk surrounding the blue compact dwarf galaxy NGC 2915. Using a combination of strong…
Outlying HII Regions in HI-Selected Galaxies
J. K. Werk, M. E. Putman, G. R. Meurer +21
We present results from the first systematic search for outlying HII regions, as part of a sample of 96 emission-line point sources (referred to as ELdots - emission-line dots) der…
An Isolated HII Region near ESO 481-G017
N. Santiago-Figueroa, M. Putman, J. Werk +2
We obtained VLA 21-cm observations of the galaxy ESO 481-G017 to determine the environment and trigger of remote star formation traced by a HII region found 43 kpc from the galaxy…
X-Ray Searches for Emission from the WHIM in the Galactic Halo and the Intergalactic Medium
Joel N. Bregman, Birgit Otte, Jimmy A. Irwin +3
At least 50% of the baryons in the local universe are undetected and predicted to be in a hot dilute phase (1E5-1E7 K) in low and moderate overdensity environments. We searched for…
