Cosmological Black Hole Observations and Kant's Transcendental Aesthetic
Juna A. Kollmeier
Kant put forward the notion of the Transcendental Aesthetic (TA) in his manuscript . In this note I review the TA in light of the detection…
Metal-Rich RRc stars in the Carnegie RR Lyrae Survey
Christopher Sneden, George W. Preston, Juna A. Kollmeier +6
We describe and employ a stacking procedure to investigate abundances derived from the low S/N spectra obtained in the Carnegie RR Lyrae Survey (CARRS; Kollmeier et al. 2013). We f…
SMHASH: Anatomy of the Orphan Stream using RR Lyrae stars
David Hendel, Victoria Scowcroft, Kathryn V. Johnston +30
Stellar tidal streams provide an opportunity to study the motion and structure of the disrupting galaxy as well as the gravitational potential of its host. Streams around the Milky…
SDSS-V: Pioneering Panoptic Spectroscopy
Juna A. Kollmeier, Gail Zasowski, Hans-Walter Rix +47
SDSS-V will be an all-sky, multi-epoch spectroscopic survey of over six million objects. It is designed to decode the history of the Milky Way, trace the emergence of the chemical…
Light Curves of the Neutron Star Merger GW170817/SSS17a: Implications for R-Process Nucleosynthesis
M. R. Drout, A. L. Piro, B. J. Shappee +41
On 2017 August 17, gravitational waves were detected from a binary neutron star merger, GW170817, along with a coincident short gamma-ray burst, GRB170817A. An optical transient so…
Early Spectra of the Gravitational Wave Source GW170817: Evolution of a Neutron Star Merger
B. J. Shappee, J. D. Simon, M. R. Drout +33
On 2017 August 17, Swope Supernova Survey 2017a (SSS17a) was discovered as the optical counterpart of the binary neutron star gravitational wave event GW170817. We report time-seri…
