A Linear Relation Between the Color Stretch and the Rising Color Slope of Type Ia Supernovae
Ping Chen, Subo Dong, Chris Ashall +34
Using data from the Complete Nearby () sample of Type Ia Supernovae (CNIa0.02), we discover a linear relation between two parameters derived from the color cur…
Final Targeting Strategy for the SDSS-IV APOGEE-2S Survey
Felipe A. Santana, Rachael L. Beaton, Kevin R. Covey +43
APOGEE is a high-resolution (R sim 22,000), near-infrared, multi-epoch, spectroscopic survey of the Milky Way. The second generation of the APOGEE project, APOGEE-2, includes an ex…
Final Targeting Strategy for the SDSS-IV APOGEE-2N Survey
Rachael L. Beaton, Ryan J. Oelkers, Christian R. Hayes +57
APOGEE-2 is a dual-hemisphere, near-infrared (NIR), spectroscopic survey with the goal of producing a chemo-dynamical mapping of the Milky Way Galaxy. The targeting for APOGEE-2 is…
Nebular Halpha emission in SN Ia 2016jae
N. Elias-Rosa, P. Chen, S. Benetti +7
There is a wide consensus that type Ia supernovae (SN Ia) originate from the thermonuclear explosion of CO white dwarfs (WD), with the lack of hydrogen in the observed spectra as a…
Visualization in Astrophysics: Developing New Methods, Discovering Our Universe, and Educating the Earth
Fangfei Lan, Michael Young, Lauren Anderson +6
We present a state-of-the-art report on visualization in astrophysics. We survey representative papers from both astrophysics and visualization and provide a taxonomy of existing a…
