Evolution of the Bar Fraction in COSMOS: Quantifying the Assembly of the Hubble Sequence
Kartik Sheth, Debra Meloy Elmegreen, Bruce G. Elmegreen +13
We have analyzed the redshift-dependent fraction of galactic bars over 0.2<z<0.84 in 2,157 luminous face-on spiral galaxies from the COSMOS 2-square degree field. Our sample is an…
Barred Galaxies at z > 0.7: NICMOS HDFN Observations
Kartik Sheth, Michael W. Regan, Nick Scoville +1
Previous optical studies found an unexpected deficit of bars at z > 0.7. To investigate the effects of bandshifting, we have studied the fraction of barred spirals in the NICMOS De…
Probing Quiescent Massive Black Holes: Insights from Tidal Disruption Events
Suvi Gezari, Linda Strubbe, Joshua S. Bloom +10
Tidal disruption events provide a unique probe of quiescent black holes in the nuclei of distant galaxies. The next generation of synoptic surveys will yield a large sample of flar…
Peer-review Platform for Astronomy Education Activities
Pedro Russo, Edward Gomez, Thilina Heenatigala +1
Hundreds of thousands of astronomy education activities exist, but their discoverability and quality is highly variable. The web platform for astronomy education activities, astroE…
Training the Next Generation of Astronomers
Peter K. G. Williams, Eric Huff, Holly Maness +28
While both society and astronomy have evolved greatly over the past fifty years, the academic institutions and incentives that shape our field have remained largely stagnant. As a…
Observational Astrophysics Research through Cross Institutional Research Partnerships
Kristen C. Dage, Linda Strubbe, Rhianna Taub +16
Undergraduate research in STEM can be a transformative experience, especially for Community College students, many of whom come from under-represented backgrounds. However, undergr…
