VLA resolves unexpected radio structures in the Perseus cluster of galaxies
Marie-Lou Gendron-Marsolais, Charles L. H. Hull, Rick Perley +10
We present new deep, high-resolution, 1.5 GHz observations of the prototypical nearby Perseus galaxy cluster from the Karl G. Jansky Very Large Array. We isolate for the first time…
Measuring Magnetic Fields Near and Far with the SKA via the Zeeman Effect
Timothy Robishaw, James A. Green, Gabriele Surcis +12
The measurement of Zeeman splitting in spectral lines---both in emission and absorption---can provide direct estimates of the magnetic field strength and direction in atomic and mo…
Observations of hydroxyl in early-type galaxies
James McBride, Katherine Alatalo, Kristina Nyland
We used Arecibo Observatory and the Green Bank Telescope to observe OH in twelve early-type galaxies with known reservoirs of dense gas. We present three new detections of OH in ab…
Parsec-scale magnetic fields in Arp 220
James McBride, Timothy Robishaw, Carl Heiles +2
We present the first very-long-baseline interferometry (VLBI) detections of Zeeman splitting in another galaxy. We used Arecibo Observatory, the Green Bank Telescope, and the Very…
Gemini Planet Imager Spectroscopy of the HR 8799 planets c and d
Patrick Ingraham, Mark S. Marley, Didier Saumon +43
During the first-light run of the Gemini Planet Imager (GPI) we obtained K-band spectra of exoplanets HR 8799 c and d. Analysis of the spectra indicates that planet d may be warmer…
Bent Radio Jets Reveal a Stripped Interstellar Medium in NGC 1272
James McBride, Michael McCourt
We report the discovery of bent double jets in the elliptical galaxy NGC 1272, a member of the Perseus cluster. The jets have a radius of curvature of ~2 kpc, much smaller than the…
The Role of Magnetic Fields in Starburst Galaxies as Revealed by OH Megamasers
James McBride, Eliot Quataert, Carl Heiles +1
We present estimates of magnetic field strengths in the interstellar media of starburst galaxies derived from measurements of Zeeman splitting associated with OH megamasers. The re…
Constraints on OH Megamaser Excitation from a Survey of OH Satellite Lines
James McBride, Carl Heiles, Moshe Elitzur
We report the results of a full-Stokes survey of all four 18 cm OH lines in 77 OH megamasers (OHMs) using the Arecibo Observatory. This is the first survey of OHMs that included ob…
An Arecibo Survey for Zeeman Splitting in OH Megamaser Galaxies
James McBride, Carl Heiles
We present the results of a comprehensive survey using the Arecibo Observatory for Zeeman splitting of OH lines in OH megamasers (OHMs). A total of seventy-seven sources were obser…
Experimental Design for the Gemini Planet Imager
James McBride, James R. Graham, Bruce Macintosh +4
The Gemini Planet Imager (GPI) is a high performance adaptive optics system being designed and built for the Gemini Observatory. GPI is optimized for high contrast imaging, combini…
Mass Accretion Rates and Histories of Dark Matter Haloes
James McBride, Onsi Fakhouri, Chung-Pei Ma
We use the extensive catalog of dark matter haloes from the Millennium simulation to investigate the statistics of the mass accretion histories (MAHs) and accretion rates of ~500,0…
