Rest-UV Absorption Lines as Metallicity Estimator: the Metal Content of Star-Forming Galaxies at z~5
A. L. Faisst, P. L. Capak, I. Davidzon +12
We measure a relation between the depth of four prominent rest-UV absorption complexes and metallicity for local galaxies and verify it up to z~3. We then apply this relation to a…
Luminosity Dependence and Redshift Evolution of Strong Emission-line Diagnostics in Star-Forming Galaxies
Lennox L. Cowie, Amy J. Barger, Antoinette Songaila
We examine the redshift evolution of standard strong emission-line diagnostics for Hbeta-selected star-forming galaxies using the local SDSS sample and a new z = 0.2 - 2.3 sample o…
Merger Signatures in the Dynamics of Star-forming Gas
Chao-Ling Hung, Christopher C. Hayward, Howard A. Smith +5
Spatially resolved kinematics have been used to determine the dynamical status of star-forming galaxies with ambiguous morphologies, and constrain the importance of galaxy interact…
Resolving Ionisation and Metallicity on Parsec Scales Across Mrk 71 with HST-WFC3

We investigate the Eddington ratio distribution of X-ray selected broad-line active galactic nuclei (AGN) in the redshift range 1.0<z<2.2, where the number density of AGNs peaks. C…
Spirality: A Novel Way to Measure Spiral Arm Pitch Angle
Douglas W. Shields, Benjamin Boe, Casey Pfountz +6
We present the MATLAB code Spirality, a novel method for measuring spiral arm pitch angles by fitting galaxy images to spiral templates of known pitch. Computation time is typicall…
ISM masses and the star formation law at Z = 1 to 6 // ALMA observations of dust continuum in 145 galaxies in the COSMOS survey field
