Instability of counter-rotating stellar disks
Robert G. Hohlfeld, Richard V. E. Lovelace
We use an N-body simulation, constructed using GADGET-2, to investigate an accretion flow onto an astrophysical disk that is in the opposite sense to the disk's rotation. In order…

Origin of the Galaxy Mass-Metallicity-Star-Formation Relation
Martin Harwit, Drew Brisbin
We describe an equilibrium model that links the metallicity of low-redshift galaxies to stellar evolution models. It enables the testing of different stellar initial mass functions…

Three-dimensional Tomography of the Galactic and Extragalactic Magnetoionic Medium with the SKA
J. L. Han, W. van Straten, T. J. W. Lazio +9
The magneto-ionic structures of the interstellar medium of the Milky Way and the intergalactic medium are still poorly understood, especially at distances larger than a few kilopar…
An Infrared Census of DUST in Nearby Galaxies with Spitzer (DUSTiNGS), II. Discovery of Metal-poor Dusty AGB Stars

The DUSTiNGS survey (DUST in Nearby Galaxies with Spitzer) is a 3.6 and 4.5 micron imaging survey of 50 nearby dwarf galaxies designed to identify dust-producing Asymptotic Giant B…
AGC198606: A gas-bearing dark matter minihalo?
E. A. K. Adams, Y. Faerman, W. F. Janesh +9
We present neutral hydrogen (HI) imaging observations with the Westerbork Synthesis Radio Telescope of AGC198606, an HI cloud discovered in the ALFALFA 21cm survey. This object is…
Strong C+ emission in galaxies at z~1-2: Evidence for cold flow accretion powered star formation in the early Universe
Drew Brisbin, Carl Ferkinhoff, Thomas Nikola +5
We have recently detected the [CII] 157.7 micron line in eight star forming galaxies at redshifts 1 to 2 using the redshift(z) Early Universe Spectrometer (ZEUS). Our sample target…
An Infrared Census of DUST in Nearby Galaxies with Spitzer (DUSTiNGS), I. Overview
Martha L. Boyer, Kristen B. W. McQuinn, Pauline Barmby +13
Nearby resolved dwarf galaxies provide excellent opportunities for studying the dust-producing late stages of stellar evolution over a wide range of metallicity (-2.7 < [Fe/H] < -1…
Star formation in Chamaeleon I and III: a molecular line study of the starless core population
A. E. Tsitali, A. Belloche, R. T. Garrod +2
The Chamaeleon clouds are excellent targets for low-mass star formation studies. Cha I and II are actively forming stars while Cha III shows no sign of ongoing star formation. We a…
The Cluster Velocity Dispersion of the Abell 2199 cD Halo of NGC 6166
Ralf Bender, John Kormendy, Mark E. Cornell +1
The Hobby-Eberly Telescope is used to measure the velocity dispersion profile of the nearest prototypical cD galaxy, NGC 6166 in cluster Abell 2199. We also present surface photome…
Searching for gravitational wave memory bursts with the Parkes Pulsar Timing Array
J. B. Wang, G. Hobbs, W. Coles +17
Anisotropic bursts of gravitational radiation produced by events such as super-massive black hole mergers leave permanent imprints on space. Such gravitational wave "memory" (GWM)…
Detection of a branched alkyl molecule in the interstellar medium: iso-propyl cyanide
Arnaud Belloche, Robin T. Garrod, Holger S. P. Müller +1
The largest non-cyclic molecules detected in the interstellar medium (ISM) are organic with a straight-chain carbon backbone. We report an interstellar detection of a branched alky…
