Abell 1033: birth of a radio phoenix
F. de Gasperin, G. A. Ogrean, R. J. van Weeren +4
Extended steep-spectrum radio emission in a galaxy cluster is usually associated with a recent merger. However, given the complex scenario of galaxy cluster mergers, many of the di…

As part of a spectroscopic survey of supernova remnant candidates in M83 using the Gemini-South telescope and GMOS, we have discovered one object whose spectrum shows very broad li…
Revised Mass-to-Light Ratios For Nearby Galaxy Groups and Clusters
Yutong Shan, Michael McDonald, Stephane Courteau
We present a detailed investigation of the cluster stellar mass-to-light (M*/L) ratio and cumulative stellar masses, derived on a galaxy-by-galaxy basis, for 12 massive (M500 ~ 10^…
Dust Attenuation in High Redshift Galaxies -- 'Diamonds in the Sky'
Nick Scoville, Andreas Faisst, Peter Capak +3
We use observed optical to near infrared spectral energy distributions (SEDs) of 266 galaxies in the COSMOS survey to derive the wavelength dependence of the dust attenuation at hi…

We investigate the effects of galaxy environment on the evolution of the quiescent fraction () from z =0.8 to 0.0 using spectroscopic redshifts and multi-wavelength i…
Estimating Black Hole Masses in Hundreds of Quasars
Nina Hernitschek, Hans-Walter Rix, Jo Bovy +1
We explore the practical feasibility of AGN broad-band reverberation mapping and present first results. We lay out and apply a rigorous approach for stochastic reverberation mappin…
Diffuse radio emission in the complex merging galaxy cluster Abell 2069
A. Drabent, M. Hoeft, R. F. Pizzo +3
Galaxy clusters with signs for a recent merger show in many cases extended diffuse radio features. This emission originates from relativistic electrons which suffer synchrotron los…
ALMA Imaging of HCN, CS and dust in Arp 220 and NGC 6240
Nick Scoville, Kartik Sheth, Fabian Walter +19
We report ALMA Band 7 (350 GHz) imaging at 0.4 - 0.6arcsec resolution and Band 9 (696 GHz) at ~0.25arcsec resolution of the luminous IR galaxies Arp 220 and NGC 6240. The long wave…
The Spectral Variability of the GHz-Peaked Spectrum Radio Source PKS 1718-649 and a Comparison of Absorption Models
S. J. Tingay, J. -P. Macquart, J. D. Collier +42
Using the new wideband capabilities of the Australia Telescope Compact Array (ATCA), we obtain spectra for PKS 1718-649, a well-known gigahertz-peaked spectrum radio source. The ob…
Serendipitous discovery of a dying Giant Radio Galaxy associated with NGC 1534, using the Murchison Widefield Array
Natasha Hurley-Walker, Melanie Johnston-Hollitt, Ron Ekers +41
Recent observations with the Murchison Widefield Array at 185~MHz have serendipitously unveiled a heretofore unknown giant and relatively nearby () radio galaxy associa…
ZFOURGE/CANDELS: On the Evolution of M* Galaxy Progenitors from z=3 to 0.5
Casey Papovich, I. Labbé, R. Quadri +38
Galaxies with stellar masses near M* contain the majority of stellar mass in the universe, and are therefore of special interest in the study of galaxy evolution. The Milky Way (MW…
Alfvenic Turbulence Beyond the Ambipolar Diffusion Scale
Blakesley Burkhart, A. Lazarian, D. Balsara +2
We investigate the nature of the Alfvénic turbulence cascade in two fluid MHD simulations in order to determine if turbulence is damped once the ion and neutral species become deco…
A Focused, Hard X-ray Look at Arp 299 with NuSTAR
A. Ptak, A. Hornschemeier, A. Zezas +19
We report on simultaneous observations of the local starburst system Arp 299 with NuSTAR and Chandra, which provides the first resolved images of this galaxy up to energies of ~ 45…
Low-resolution Spectroscopy for the Globular Clusters with Signs of Supernova Enrichment: M22, NGC 1851 and NGC 288
Dongwook Lim, Sang-Il Han, Young-Wook Lee +5
There is increasing evidence for the presence of multiple red giant branches (RGBs) in the color-magnitude diagrams of massive globular clusters (GCs). In order to investigate the…
Characteristics of Spiral Arms in Late-type Galaxies
Z. N. Honig, M. J. Reid
We have measured the positions of large numbers of H II regions in four nearly face-on, late-type, spiral galaxies: NGC 628 (M 74), NGC 1232, NGC 3184 and NGC 5194 (M 51). Fitting…
