Galactic halo gas traces inflowing star-formation fuel and feedback from a galaxy's disk and is therefore crucial to our understanding of galaxy evolution. In this review, we summarize the…
Candidate RR Lyrae Stars Found in Sloan Digital Sky Survey Commissioning Data
We present a sample of 148 candidate RR Lyrae stars selected from Sloan Digital Sky Survey (SDSS) commissioning data for about 100 deg2 of sky surveyed twice with Δt = 1.9946 days. Although the…
THE OPTICAL–INFRARED EXTINCTION CURVE AND ITS VARIATION IN THE MILKY WAY

- 11 February 2016
The dust extinction curve is a critical component of many observational programs and an important diagnostic of the physics of the interstellar medium. Here we present new measurements of the dust…
THE DISRUPTION AND FUELING OF M33
The disruption of the M33 galaxy is evident from its extended gaseous structure. We present new data from the Galactic Arecibo L-Band Feed Array H i (GALFA-H i) Survey that show the full extent and…
An Accurate Distance to High-Velocity Cloud Complex C
We report an accurate distance of d = 10 ± 2.5 kpc to the high-velocity cloud Complex C. Using high signal-to-noise ratio Keck HIRES spectra of two horizontal-branch stars, we have detected Ca II K…
A Parallactic Distance of 389-21+24 Parsecs to the Orion Nebula Cluster from Very Long Baseline Array Observations

- Physics
- 15 June 2007
We determine the parallax and proper motion of the flaring, nonthermal radio star GMR A, a member of the Orion Nebula Cluster, using Very Long Baseline Array observations. Based on the parallax, we…
THE GALFA-Hi SURVEY: DATA RELEASE 1
We present the Galactic Arecibo L-Band Feed Array H i (GALFA-H i) survey and its first full data release (DR1). GALFA-H i is a high-resolution (∼4′), large-area (13,000 deg2), high spectral…
A HIGH-RESOLUTION STUDY OF THE H i–H2 TRANSITION ACROSS THE PERSEUS MOLECULAR CLOUD
- Min-Young Lee, S. Stanimirović, D. Saul
- Physics
- 12 October 2011
To investigate the fundamental principles of H2 formation in a giant molecular cloud, we derive the H i and H2 surface density (ΣH i and ΣH2) images of the Perseus molecular cloud on sub-pc scales…
Neutral Hydrogen Structures Trace Dust Polarization Angle: Implications for Cosmic Microwave Background Foregrounds.
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 magnetic field…
