Very-high-energy gamma-ray observations of the Type Ia Supernova SN 2014J with the MAGIC telescopes

Thomas Günther Bretz

Context. In this work we present data from observations with the MAGIC telescopes of SN 2014J detected on January 21 2014, the closest Type Ia supernova since Imaging Air Cherenkov Telescopes started to operate. Aims. We aim to probe the possibility of ver ...

Observations of Sagittarius A* during the pericenter passage of the G2 object with MAGIC

Thomas Günther Bretz

Context. We present the results of a multi-year monitoring campaign of the Galactic center (GC) with the MAGIC telescopes. These observations were primarily motivated by reports that a putative gas cloud (G2) would be passing in close proximity to the supe ...

The formation of the Milky Way halo and its dwarf satellites; a NLTE-1D abundance analysis II. Early chemical enrichment

Pascale Jablonka, Pierre North

We present the non-local thermodynamic equilibrium (NLTE) abundances of up to 10 chemical species in a sample of 59 very metal-poor (VMP, -4

Toward an Internally Consistent Astronomical Distance Scale

Frédéric Courbin

Accurate astronomical distance determination is crucial for all fields in astrophysics, from Galactic to cosmological scales. Despite, or perhaps because of, significant efforts to determine accurate distances, using a wide range of methods, tracers, and t ...

High-redshift supernova rates measured with the gravitational telescope A 1689

Jean-Paul Richard Kneib, Johan Richard

Aims. We present a ground-based, near-infrared search for lensed supernovae behind the massive cluster Abell 1689 at z = 0.18, which is one of the most powerful gravitational telescopes that nature provides. Methods. Our survey was based on multi-epoch J-b ...

The 0.1 < z < 1.65 evolution of the bright end of the [O II] luminosity function

Jean-Paul Richard Kneib, Johan Comparat, Timothée Guy Olivier Delubac, Jun Ma, David Schlegel, Johan Richard, Zhenyu Wu

We present the [O II] (lambda lambda 3729; 3726) luminosity function measured in the redshift range 0.1 < z < 1.65 with unprecedented depth and accuracy. Our measurements are based on medium resolution flux-calibrated spectra of emission line galaxies with ...

The behaviour of dark matter associated with four bright cluster galaxies in the 10 kpc core of Abell 3827

David Richard Harvey, Mathilde Jauzac, Richard Massey, Johan Richard

Galaxy cluster Abell 3827 hosts the stellar remnants of four almost equally bright elliptical galaxies within a core of radius 10 kpc. Such corrugation of the stellar distribution is very rare, and suggests recent formation by several simultaneous mergers. ...

Superdiffusive transport in laboratory and astrophysical plasmas

Ambrogio Fasoli, Ivo Furno, Paolo Ricci, Kyle Gustafson, Alexandre Dominique Bovet

In the last few years it has been demonstrated, both by data analysis and by numerical simulations, that the transport of energetic particles in the presence of magnetic turbulence can be superdiffusive rather than normal diffusive (Gaussian). The term ‘su ...

Analysis of the Atomic Layer Deposited Al2O3 field-effect passivation in black silicon

Anna Fontcuberta i Morral, Sonia Conesa Boj

We demonstrate that n-type black silicon can be passivated efficiently using Atomic Layer Deposited (ALD) Al2O3, reaching maximum surface recombination velocities below 7 cm/s. We show that the low surface recombination velocity results from a higher sensi ...
