Ages of Type Ia Supernovae Over Cosmic Time
Michael J. Childress, Christian Wolf, H. Jabran Zahid
We derive empirical models for galaxy mass assembly histories, and convolve these with theoretical delay time distribution (DTD) models for Type Ia supernovae (SNe Ia) to derive th…
The FMOS-Cosmos Survey of Star-Forming Galaxies at z~1.6 II. The Mass-Metallicity Relation and the Dependence on Star Formation Rate and Dust Extinction
H. J. Zahid, D. Kashino, J. D. Silverman +28
We investigate the relationships between stellar mass, gas-phase oxygen abundance (metallicity), star formation rate, and dust content of star-forming galaxies at z1.6 using…
The FMOS-COSMOS survey of star-forming galaxies at z ~ 1.6. I. Hα-based star formation rates and dust extinction
D. Kashino, J. D. Silverman, G. Rodighiero +26
We present the first results from a near-IR spectroscopic survey of the COSMOS field, using the Fiber Multi-Object Spectrograph on the Subaru telescope, designed to characterize th…
Empirical Constraints for the Magnitude and Composition of Galactic Winds
H. Jabran Zahid, Paul Torrey, Mark Vogelsberger +3
Galactic winds are a key physical mechanism for understanding galaxy formation and evolution, yet empirical and theoretical constraints for the character of winds are limited and d…
The Slow Flow Model of Dust Efflux in Local Star-Forming Galaxies
H. Jabran Zahid, Paul Torrey, Rolf Kudritzki +3
We develop a dust efflux model of radiation pressure acting on dust grains which successfully reproduces the relation between stellar mass, dust opacity and star formation rate obs…
The Chemical Evolution of Star-Forming Galaxies Over the Last 11 Billion Years
H. Jabran Zahid, Margaret Geller, Lisa Kewley +3
We calculate the stellar mass-metallicity relation at five epochs ranging to z~2.3. We quantify evolution in the shape of the mass-metallicity relation as a function of redshift; t…
The Observed Relation between Stellar Mass, Dust Extinction and Star Formation Rate in Local Galaxies
H. Jabran Zahid, Robert M. Yates, Lisa J. Kewley +1
In this study we investigate the relation between stellar mass, dust extinction and star formation rate (SFR) using ~150,000 star-forming galaxies from the SDSS DR7. We show that t…
A Census of Oxygen in Star-Forming Galaxies: An Empirical Model Linking Metallicities, Star Formation Rates and Outflows
H. Jabran Zahid, Gabriel I. Dima, Lisa J. Kewley +2
In this contribution we present the first census of oxygen in star-forming galaxies in the local universe. We examine three samples of galaxies with metallicities and star formatio…
The Metallicities of Low Stellar Mass Galaxies and the Scatter in the Mass-Metallicity Relation
H. J. Zahid, F. Bresolin, L. J. Kewley +2
In this investigation we quantify the metallicities of low mass galaxies by constructing the most comprehensive census to date. We use galaxies from the SDSS and DEEP2 survey and e…
Eliminating Error in the Chemical Abundance Scale for Extragalactic HII Regions
Angel R. Lopez-Sanchez, M. A. Dopita, L. J. Kewley +3
In an attempt to remove the systematic errors which have plagued the calibration of the HII region abundance sequence, we have theoretically modeled the extragalactic HII region se…
Reexamination of the Radial Abundance Gradient Break in NGC 3359
H. Jabran Zahid, Fabio Bresolin
In this contribution, we reexamine the radial oxygen abundance gradient in the strongly barred spiral galaxy NGC 3359, for which, using an imaging spectrophotometric technique, Mar…
Metallicity Gradients and Gas Flows in Galaxy Pairs
Lisa J. Kewley, David Rupke, H. Jabran Zahid +2
We present the first systematic investigation into the metallicity gradients in galaxy close pairs. We determine the metallicity gradients for 8 galaxies in close pairs using HII r…
The Mass-Metallicity and Luminosity-Metallicity Relation from DEEP2 at z ~ 0.8
H. J. Zahid, L. J. Kewley, F. Bresolin
We present the mass-metallicity (MZ) and luminosity-metallicity (LZ) relations at z ~ 0.8 from ~1350 galaxies in the Deep Extragalactic Evolutionary Probe 2 (DEEP2) survey. We dete…
