The NIFTY way of Bayesian signal inference
Marco Selig
We introduce NIFTY, "Numerical Information Field Theory", a software package for the development of Bayesian signal inference algorithms that operate independently from any underly…
Biased Tracers and Time Evolution
Mehrdad Mirbabayi, Fabian Schmidt, Matias Zaldarriaga
We study the effect of time evolution on galaxy bias. We argue that at any order in perturbations, the galaxy density contrast can be expressed in terms of a finite set of locally…
Spectroscopy of the Type Ia supernova 2011fe past 1000 days
S. Taubenberger, N. Elias-Rosa, W. E. Kerzendorf +11
In this letter we present an optical spectrum of SN 2011fe taken 1034 d after the explosion, several hundred days later than any other spectrum of a Type Ia supernova (disregarding…
Ultraviolet Spectroscopy of Type IIb Supernovae: Diversity and the Impact of Circumstellar Material
Sagi Ben-Ami, Stephan Hachinger, Avishay Gal-Yam +9
We present new Hubble Space Telescope (HST) multi-epoch ultraviolet (UV) spectra of the bright Type IIb SN 2013df, and undertake a comprehensive anal- ysis of the set of four Type…
Modelling galaxy spectra in presence of interstellar dust-III. From nearby galaxies to the distant Universe
Letizia P. Cassarà, Lorenzo Piovan, Cesare Chiosi
Improving upon the standard evolutionary population synthesis (EPS) technique, we present spectrophotometric models of galaxies whose morphology goes from spherical structures to d…
The nature of obscuration in AGN: II. insights from clustering properties
Li Shao, Cheng Li, Guinevere Kauffmann +1
Based on large optical and mid-infrared (IR) surveys, we investigate the relation between nuclear activity in local Seyfert 2 galaxies and galaxy interactions using a statistical n…
The SILCC (SImulating the LifeCycle of molecular Clouds) project: I. Chemical evolution of the supernova-driven ISM
S. K. Walch, P. Girichidis, T. Naab +7
The SILCC project (SImulating the Life-Cycle of molecular Clouds) aims at a more self-consistent understanding of the interstellar medium (ISM) on small scales and its link to gala…
Local Group galaxies emerge from the dark
Till Sawala, Carlos S. Frenk, Azadeh Fattahi +13
The "Lambda Cold Dark Matter" (LCDM) model of cosmic structure formation is eminently falsifiable: once its parameters are fixed on large scales, it becomes testable in the nearby…
Overview of the SDSS-IV MaNGA Survey: Mapping Nearby Galaxies at Apache Point Observatory
Kevin Bundy, Matthew A. Bershady, David R. Law +65
We present an overview of a new integral field spectroscopic survey called MaNGA (Mapping Nearby Galaxies at Apache Point Observatory), one of three core programs in the fourth-gen…
INTEGRAL 11-year hard X-ray survey above 100 keV
Roman A. Krivonos, Sergey S. Tsygankov, Alexander A. Lutovinov +3
We present results of all sky survey, performed with data acquired by the IBIS telescope onboard the INTEGRAL observatory over eleven years of operation, at energies above 100 keV.…
5.9 keV Mn K-shell X-ray luminosity from the decay of 55Fe in Type Ia supernova models
I. R. Seitenzahl, A. Summa, F. Krauss +12
We show that the X-ray line flux of the Mn Kalpha line at 5.9 keV from the decay of 55Fe is a promising diagnostic to distinguish between Type Ia supernova (SN Ia) explosion models…
All-sky reconstruction of the primordial scalar potential from WMAP temperature data
Sebastian Dorn, Maksim Greiner, Torsten A. Enßlin
An essential quantity required to understand the physics of the early Universe, in particular the inflationary epoch, is the primordial scalar potential and its statistics. We…
Quasi-stationary solutions of self-gravitating scalar fields around black holes
Nicolas Sanchis-Gual, Juan Carlos Degollado, Pedro J. Montero +1
Recent perturbative studies have shown the existence of long-lived, quasi-stationary configurations of scalar fields around black holes. In particular, such configurations have bee…
Supernova 1987A: neutrino-driven explosions in three dimensions and light curves
Victor Utrobin, Annop Wongwathanarat, H. -Thomas Janka +1
The well-studied type IIP SN 1987A, produced by the explosion of a blue supergiant (BSG) star, is a touchstone for massive-star evolution, simulations of neutrino-driven explosions…
The variation in molecular gas depletion time among nearby galaxies: II the impact of galaxy internal structures
Mei-Ling Huang, Guinevere Kauffmann
We use a data set of nearby galaxies drawn from the HERACLES, ATLAS3D, and COLD GASS surveys to study variations in molecular gas depletion time (Tdep) in galaxy structures such as…
Supernova deleptonization asymmetry: Impact on self-induced flavor conversion
Sovan Chakraborty, Georg Raffelt, Hans-Thomas Janka +1
During the accretion phase of a core-collapse supernova (SN), the deleptonization flux has recently been found to develop a global dipole pattern (LESA---Lepton Emission Self-susta…
The dynamical evolution of molecular clouds near the Galactic Centre - I. Orbital structure and evolutionary timeline
J. M. Diederik Kruijssen, James E. Dale, Steven N. Longmore
We recently proposed that the star-forming potential of dense molecular clouds in the Central Molecular Zone (CMZ, i.e. the central few 100 pc) of the Milky Way is linked to their…
New constraints on gravity from clusters of galaxies
Matteo Cataneo, David Rapetti, Fabian Schmidt +6
The abundance of massive galaxy clusters is a powerful probe of departures from General Relativity (GR) on cosmic scales. Despite current stringent constraints placed by stellar an…
Instability of Magnetic Equilibria in Barotropic Stars
J. P. Mitchell, J. Braithwaite, A. Reisenegger +3
In stably stratified stars, numerical magneto-hydrodynamics simulations have shown that arbitrary initial magnetic fields evolve into stable equilibrium configurations, usually con…

A. Nelles, P. Schellart, S. Buitink +66
Measuring radio emission from air showers offers a novel way to determine properties of the primary cosmic rays such as their mass and energy. Theory predicts that relativistic tim…
