We present 25 arcsecond resolution radio images of five Lynds Dark Nebulae (L675, L944, L1103, L1111 & L1246) at 16 GHz made with the Arcminute Microkelvin Imager (AMI) Large Array…
Evidence for a Triaxial Milky Way Dark Matter Halo from the Sagittarius Stellar Tidal Stream
David R. Law, Steven R. Majewski, Kathryn V. Johnston
Observations of the lengthy tidal streams produced by the destruction of the Sagittarius dwarf spheroidal (Sgr dSph) are capable of providing strong constraints on the shape of the…

We present a catalog of 5184 candidate infrared counterparts to X-ray sources detected towards the Galactic center. The X-ray sample contains 9017 point sources detected in this re…
Radio detection of LAT PSRs J1741-2054 and J2032+4127: no longer just gamma-ray pulsars
F. Camilo, P. S. Ray, S. M. Ransom +24
Sixteen pulsars have been discovered so far in blind searches of photons collected with the Large Area Telescope on the Fermi Gamma-ray Space Telescope. We here report the discover…
Out of the frying pan: a young pulsar with a long radio trail emerging from SNR G315.9-0.0
F. Camilo, C. -Y. Ng, B. M. Gaensler +4
The faint radio supernova remnant SNR G315.9-0.0 is notable for a long and thin trail that extends outward perpendicular from the edge of its approximately circular shell. In a sea…
The Accretion of Fuel at the Disk-Halo Interface
M. E. Putman, J. E. G. Peek, F. Heitsch
We discuss the support for the cooling of gas directly at the disk-halo interface as a mechanism to continually fuel a galaxy. This may be an important reservoir as there is not en…
Discovery of the energetic pulsar J1747-2809 in the supernova remnant G0.9+0.1
F. Camilo, S. M. Ransom, B. M. Gaensler +1
The supernova remnant G0.9+0.1 has long been inferred to contain a central energetic pulsar. In observations with the NRAO Green Bank Telescope at 2 GHz, we have detected radio pul…
An OSIRIS study of the gas kinematics in a sample of UV-selected galaxies: Evidence of "Hot and Bothered" starbursts in the local Universe
Antara R. Basu-Zych, Thiago S. Goncalves, Roderik Overzier +6
We present data from Integral Field Spectroscopy for 3 supercompact UV-Luminous Galaxies (ScUVLGs). As nearby (z~0.2), compact (R_50~1-2 kpc), bright Paschen-alpha sources, with un…
Studying Large and Small Scale Environments of Ultraviolet Luminous Galaxies
Antara R. Basu-Zych, David Schiminovich, Sebastien Heinis +23
Studying the environments of 0.4<z<1.2 UV-selected galaxies, as examples of extreme star-forming galaxies (with star formation rates in the range of 3-30 M_sol/yr), we explore the…
A Near-Infrared Survey of the Inner Galactic Plane for Wolf-Rayet Stars I. Methods and First Results: 41 New WR Stars
Michael M. Shara, Anthony F. J. Moffat, Jill Gerke +6
The discovery of new Wolf-Rayet (WR) stars in our Galaxy via large-scale narrowband optical surveys has been severely limited by dust extinction. Recent improvements in infrared te…
The disc-dominated host galaxy of FR-I radio source B2 0722+30
B. H. C. Emonts, C. N. Tadhunter, R. Morganti +4
We present new observational results that conclude that the nearby radio galaxy B2 0722+30 is one of the very few known disc galaxies in the low-redshift Universe that host a class…
The Fate of High-Velocity Clouds: Warm or Cold Cosmic Rain?
Fabian Heitsch, Mary E. Putman
We present two sets of grid-based hydrodynamical simulations of high-velocity clouds (HVCs) traveling through the diffuse, hot Galactic halo. These HI clouds have been suggested to…
New Young Planetary Nebulae in IPHAS
K. Viironen, A. Mampaso, R. L. M. Corradi +12
We search for very small-diameter galactic planetary nebulae (PNe) representing the earliest phases of PN evolution. A recently published IPHAS catalogue of Ha-emitting stars provi…
Electron-ion Recombination of Fe X forming Fe IX and of Fe XI forming Fe X: Laboratory Measurements and Theoretical Calculations
M. Lestinsky, N. R. Badnell, D. Bernhardt +12
We have measured electron-ion recombination for Fe forming Fe and for Fe forming Fe using merged beams at the TSR heavy-ion storage-ring in Heidelberg.…
A peculiar HI cloud near the distant globular cluster Pal 4
Jacco Th. van Loon, Snezana Stanimirovic, Mary Putman +4
We present 21-cm observations of four Galactic globular clusters, as part of the on-going GALFA-HI Survey at Arecibo. We discovered a peculiar HI cloud in the vicinity of the dista…
The Runaway White Dwarf LP400-22 Has a Companion
Mukremin Kilic, Warren R. Brown, Carlos Allende Prieto +4
We report the detection of a radial velocity companion to the extremely low mass white dwarf LP400-22. The radial velocity of the white dwarf shows variations with a semi-amplitude…
Gas infall towards Sgr A* from the clumpy circumnuclear disk
María Montero-Castaño, Robeson M. Herrnstein, Paul T. P. Ho
We present the first large-scale mosaic performed with the Submillimeter Array (SMA) in the Galactic center. We have produced a 25-pointing mosaic, covering a ~2' x 2' area around…
Probing the Galactic Potential with Next-Generation Observations of Disk Stars
