High resolution mid-infrared spectra are presented for 155 nuclear and extranuclear regions from the Spitzer Infrared Nearby Galaxies Survey (SINGS). The fluxes for nine atomic for…
Dwarf Galaxy Starburst Statistics in the Local Volume
Janice C. Lee, Robert C. Kennicutt, José G. Funes S. J. +2
An unresolved question in galaxy evolution is whether the star formation histories of low mass systems are preferentially dominated by starbursts or modes that are more quiescent a…
Multi-Scale CLEAN: A comparison of its performance against classical CLEAN in galaxies using THINGS
J. W. Rich, W. J. G. de Blok, T. J. Cornwell +4
A practical evaluation of the Multi-Scale CLEAN algorithm is presented. The data used in the comparisons are taken from The HI Nearby Galaxy Survey (THINGS). The implementation of…
Super Star Clusters in SBS0335-052E
Rodger I. Thompson, Marc Sauvage, Robert C. Kennicutt +3
As one of the lowest metallicity star forming galaxies, with a nucleus of several super star clusters, SBS0335-052E is the subject of substantial current study. We present new insi…
Geometrically Derived Timescales for Star Formation in Spiral Galaxies
D. Tamburro, H. -W. Rix, F. Walter +4
We estimate a characteristic timescale for star formation in the spiral arms of disk galaxies, going from atomic hydrogen (HI) to dust-enshrouded massive stars. Drawing on high-res…
Are the kinematics of DLAs in agreement with their arising in the gas disks of galaxies?
Martin Zwaan, Fabian Walter, Emma Ryan-Weber +3
We demonstrate in this paper that the velocity widths of the neutral gas in Damped Ly Alpha (DLA) systems are inconsistent with these systems originating in gas disks of galaxies s…
Dynamical Centers and Non-Circular Motions in THINGS Galaxies: Implications for Dark Matter Halos
C. Trachternach, W. J. G. de Blok, F. Walter +2
We present harmonic decompositions of the velocity fields of 19 galaxies from THINGS (The \HI Nearby Galaxy Survey) which quantify the magnitude of the non-circular motions in thes…
THINGS: The HI Nearby Galaxy Survey
F. Walter, E. Brinks, W. J. G. de Blok +4
We present "The HI Nearby Galaxy Survey (THINGS)", a high spectral (<=5.2 km/s) and spatial (~6") resolution survey of HI emission in 34 nearby galaxies obtained using the NRAO Ver…
High-resolution dark matter density profiles of THINGS dwarf galaxies: Correcting for non-circular motions
Se-Heon Oh, W. J. G. de Blok, Fabian Walter +2
We present a new method to remove the impact of random and small-scale non-circular motions from HI velocity fields in galaxies in order to better constrain the dark matter propert…
Tracing spiral density waves in M81
S. Kendall, R. C. Kennicutt, C. Clarke +1
We use SPITZER IRAC 3.6 and 4.5micron near infrared data from the Spitzer Infrared Nearby Galaxies Survey (SINGS), optical B, V and I and 2MASS Ks band data to produce mass surface…
Isolated OB Associations in Stripped HI Gas Clouds
J. K. Werk, M. E. Putman, G. R. Meurer +4
HST ACS/HRC images in UV (F250W), V (F555W), and I (F814W) resolve three isolated OB associations that lie up to 30 kpc from the stellar disk of the S0 galaxy NGC 1533. Previous na…
NICMOS Measurements of the Near Infrared Background
Rodger I. Thompson, Daniel Eisenstein, Xiaohui Fan +2
This paper addresses the nature of the near infrared background. We investigate whether there is an excess background at 1.4 microns, what is the source of the near infrared backgr…
Extended UV (XUV) Emission in Nearby Galaxy Disks
A. Gil de Paz, D. A. Thilker, L. Bianchi +19
We summarize the main properties of the extended UV (XUV) emission found in roughly 30% of the nearby spiral galaxies observed by the GALEX satellite. Two different classes of XUV…
The Star Formation Demographics of Galaxies in the Local Volume
Janice C. Lee, Robert C. Kennicutt, Jose G. Funes +3
We examine the connections between the current global star formation activity, luminosity, dynamical mass and morphology of galaxies in the Local Volume, using H-alpha data from th…
Spectral Mapping Reconstruction of Extended Sources
J. D. T. Smith, L. Armus, D. A. Dale +6
Three dimensional spectroscopy of extended sources is typically performed with dedicated integral field spectrographs. We describe a method of reconstructing full spectral cubes, w…
Star Formation in NGC 5194 (M51a). II. The Spatially-Resolved Star Formation Law
Robert C. Kennicutt, Daniela Calzetti, Fabian Walter +20
We have studied the relationship between the star formation rate (SFR) surface density and gas surface density in the spiral galaxy M51a (NGC 5194), using multi-wavelength data obt…
Gaps in the cloud cover? Comparing extinction measures in spiral disks
B. W. Holwerda, M. Meyer, M. Regan +11
Dust in galaxies can be mapped by either the FIR/sub-mm emission, the optical or infrared reddening of starlight, or the extinction of a known background source. We compare two dus…
