Preserving Structure in Multi-wavelength Images of Extended Objects
James Pizagno
A non-parametric smoothing method is presented that reduces noise in multi-wavelength imaging data sets. Using Principle Component Analysis (hereafter PCA) to associate pixels acco…
The Tully-Fisher Relation and Its Residuals for a Broadly Selected Sample of Galaxies
James Pizagno, Francisco Prada, David H. Weinberg +7
We measure the relation between galaxy luminosity and disk circular velocity (the Tully-Fisher [TF] relation), in the g, r, i, and z-bands, for a broadly selected sample of galaxie…
Dark Matter Halos of Disk Galaxies: Constraints from the Tully-Fisher Relation
Oleg Y. Gnedin, David H. Weinberg, James Pizagno +2
We investigate structural properties of dark matter halos of disk galaxies in LCDM cosmology, using a well-defined sample of 81 disk-dominated galaxies from the SDSS redshift surve…
Dark Matter and Stellar Mass in the Luminous Regions of Disk Galaxies
James Pizagno, Francisco Prada, David H. Weinberg +7
We investigate the correlations among stellar mass (M_*), disk scale length (R_d), and rotation velocity at 2.2 disk scale lengths (V_2.2) for a sample of 81 disk-dominated galaxie…
Rotation Velocities of Two Low Luminosity Field Galaxies
James Pizagno, Michael R. Blanton, David H. Weinberg +2
We present H-alpha rotation curves of two low luminosity field galaxies with r-band absolute magnitudes M_r=-13.9^{+0.8}_{-0.5} and M_r=-14.7^{+0.3}_{-0.2} (for h=0.7; the large er…
The Extinction Distribution in the Galaxy UGC 5041
James Pizagno, Hans-Walter Rix
We probe the dust extinction through the foreground disk of the overlapping galaxy pair UGC 5041 by analyzing B,I, and H band images. The inclined foreground disk of this infrared-…
