Non-ideal magnetohydrodynamics on a moving mesh

Federico Marinacci, Mark Vogelsberger, Rahul Kannan +3

In certain astrophysical systems the commonly employed ideal magnetohydrodynamics (MHD) approximation breaks down. Here, we introduce novel explicit and implicit numerical schemes…

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…

Tree-based solvers for adaptive mesh refinement code FLASH - I: gravity and optical depths

Richard Wünsch, Stefanie Walch, František Dinnbier +1

We describe an OctTree algorithm for the MPI-parallel, adaptive mesh-refinement code {\sc FLASH}, which can be used to calculate the gas self-gravity, and also the angle-averaged l…

Exploring Cosmic Origins with CORE: Survey requirements and mission design

J. Delabrouille, P. de Bernardis, F. R. Bouchet +200

Future observations of cosmic microwave background (CMB) polarisation have the potential to answer some of the most fundamental questions of modern physics and cosmology. In this p…

Inelastic e+Mg collision data and its impact on modelling stellar and supernova spectra

P. S. Barklem, Y. Osorio, D. V. Fursa +4

Results of calculations for inelastic e+Mg effective collision strengths for the lowest 25 physical states of Mg I (up to 3s6p 1P), and thus 300 transitions, from the convergent cl…

COSMOGRAIL XVI: Time delays for the quadruply imaged quasar DES J0408-5354 with high-cadence photometric monitoring

F. Courbin, V. Bonvin, E. Buckley-Geer +74

We present time-delay measurements for the new quadruply imaged quasar DES J0408-5354, the first quadruply imaged quasar found in the Dark Energy Survey (DES). Our result is made p…

The Hyper Suprime-Cam SSP Survey: Overview and Survey Design

H. Aihara, N. Arimoto, R. Armstrong +139

Hyper Suprime-Cam (HSC) is a wide-field imaging camera on the prime focus of the 8.2m Subaru telescope on the summit of Maunakea in Hawaii. A team of scientists from Japan, Taiwan…
