Eric C. Bellm, Shrinivas R. Kulkarni, Matthew J. Graham +112
The Zwicky Transient Facility (ZTF) is a new optical time-domain survey that uses the Palomar 48-inch Schmidt telescope. A custom-built wide-field camera provides a 47 deg fiel…
: Estimating Transient Discovery Rates for the Zwicky Transient Facility
Ulrich Feindt, Jakob Nordin, Mickael Rigault +4
When planning a survey for astronomical transients, many factors such as cadence, filter choice, sky coverage, and depth of observations need to be balanced in order to optimize th…
Multi-Messenger Astrophysics: Harnessing the Data Revolution
Gabrielle Allen, Warren Anderson, Erik Blaufuss +27
The past year has witnessed discovery of the first identified counterparts to a gravitational wave transient (GW 170817A) and a very high-energy neutrino (IceCube-170922A). These s…
SCALA: In-situ calibration for Integral Field Spectrographs
S. Lombardo, D. Küsters, M. Kowalski +39
The scientific yield of current and future optical surveys is increasingly limited by systematic uncertainties in the flux calibration. This is the case for Type Ia supernova (SN I…
The IceCube Neutrino Observatory: Instrumentation and Online Systems
IceCube Collaboration, M. G. Aartsen, M. Ackermann +350
The IceCube Neutrino Observatory is a cubic-kilometer-scale high-energy neutrino detector built into the ice at the South Pole. Construction of IceCube, the largest neutrino detect…

Gen2 Collaboration, M. G. Aartsen, K. Abraham +337
Papers submitted to the 34th International Cosmic Ray Conference (ICRC 2015, The Hague) by the IceCube-Gen2 Collaboration.
Search for dark matter in the hidden-photon sector with a large spherical mirror
The FUNK Experiment, :, Darko Veberič +11
If dark matter consists of hidden-sector photons which kinetically mix with regular photons, a tiny oscillating electric-field component is present wherever we have dark matter. In…
