The Mass Dependence of Star Formation Histories in Barred Spiral Galaxies
Christian Carles, Hugo Martel, Sara L. Ellison +1
We performed a series of 29 gasdynamical simulations of disc galaxies, barred and unbarred, with various stellar masses, to study the impact of the bar on star formation history. U…
Pattern recognition in the ALFALFA.70 and Sloan Digital Sky Surveys: A catalog of 500,000 HI gas fraction estimates based on artificial neural networks
Hossen Teimoorinia, Sara L. Ellison, David R. Patton
The application of artificial neural networks (ANNs) for the estimation of HI gas mass fraction (\fgas) is investigated, based on a sample of 13,674 galaxies in the Sloan Digital S…
Chemical abundances of damped Lyman alpha systems in the XQ-100 survey
T. A. M. Berg, S. L. Ellison, R. Sanchez-Ramirez +8
The XQ-100 survey has provided high signal-noise spectra of 100 redshift 3-4.5 quasars with the X-Shooter spectrograph. The metal abundances for 13 elements in the 41 damped Lyman…
From Exoplanets to Quasars: Detection of Potential Damped Lyman Alpha Absorbing Galaxies Using Angular Differential Imaging
Mara Johnson-Groh, Christian Marois, Sara L. Ellison
The advantages of angular differential imaging (ADI) has been previously untested in imaging the host galaxies of damped Lyman alpha (DLA) systems. In this pilot study, we present…
The impact of galactic properties and environment on the quenching of central and satellite galaxies: A comparison between SDSS, Illustris and L-Galaxies
Asa F. L. Bluck, J. Trevor Mendel, Sara L. Ellison +7
We quantify the impact that a variety of galactic and environmental properties have on the quenching of star formation. We collate a sample of 400,000 central and 100…
Galaxy pairs in the Sloan Digital Sky Survey - XI. A new method for measuring the influence of the closest companion out to wide separations
David R. Patton, Farid D. Qamar, Sara L. Ellison +5
We describe a statistical approach for measuring the influence that a galaxy's closest companion has on the galaxy's properties out to arbitrarily wide separations. We begin by ide…
Nature and statistical properties of quasar associated absorption systems in the XQ-100 Legacy Survey
Serena Perrotta, Valentina D'Odorico, J. Xavier Prochaska +12
We statistically study the physical properties of a sample of narrow absorption line (NAL) systems looking for empirical evidences to distinguish between intrinsic and intervening…
An Artificial Neural Network Approach For Ranking Quenching Parameters In Central Galaxies
Hossen Teimoorinia, Asa F. L. Bluck, Sara L. Ellison
We present a novel technique for ranking the relative importance of galaxy properties in the process of quenching star formation. Specifically, we develop an artificial neural netw…
