Eight Ultra-faint Galaxy Candidates Discovered in Year Two of the Dark Energy...

We report the discovery of eight new ultra-faint dwarf galaxy candidates in the second year of optical imaging data from the Dark Energy Survey (DES). Six of these candidates are detected at high...

Beam calibration of radio telescopes with drones [Replacement]

We present a multi-frequency far-field beam map for the 5m dish telescope at the Bleien Observatory measured using a commercially available drone. We describe the hexacopter drone used in this...

Crowdfunding Astronomy with Google Sky [Replacement]

For nearly four years, NASA's Kepler space telescope searched for planets like the Earth around more than 150,000 stars similar to the Sun. In 2008 with in-kind support from several technology...

Identification of the ~3.55 keV emission line candidate objects across the...

Emission line at the energy ~3.55 keV detected in different galaxies and galaxy clusters has caused a lot of discussion in high-energy astrophysics and particle physics communities. To reveal the...

Astrophysical calibration of gravitational-wave detectors

We investigate a method to assess the validity of gravitational-wave detector calibration through the use of gamma-ray bursts as standard sirens. Such signals, as measured via gravitational-wave...

Observation of polarised hard X-ray emission from the Crab by the PoGOLite...

We have measured the linear polarisation of hard X-ray emission from the Crab in a previously unexplored energy interval, 20-120 keV. The introduction of two new observational parameters, the...

Tiling strategies for optical follow-up of gravitational wave triggers by...

The advanced LIGO and Virgo detectors scheduled to come online in the next two years will open up the much anticipated era of gravitational wave astronomy. Among the strongest contenders for the first...

Lumped element kinetic inductance detectors maturity for space-borne...

This work intends to give the state-of-the-art of our knowledge of the performance of LEKIDs at millimetre wavelengths (from 80 to 180~GHz). We evaluate their optical sensitivity under typical...

Resolving the HD 100546 Protoplanetary System with the Gemini Planet Imager:...

We report Gemini Planet Imager H band high-contrast imaging/integral field spectroscopy and polarimetry of the HD 100546, a 10 $Myr$-old early-type star recently confirmed to host a thermal infrared...

The data sharing advantage in astrophysics

We present here evidence for the existence of a citation advantage within astrophysics for papers that link to data. Using simple measures based on publication data from NASA Astrophysics Data System...

Frequentist tests for Bayesian models

Analogues of the frequentist chi-square and $F$ tests are proposed for testing goodness-of-fit and consistency for Bayesian models. Simple examples exhibit these tests' detection of inconsistency...

HARPS-N observes the Sun as a star

Radial velocity perturbations induced by stellar surface inhomogeneities including spots, plages and granules currently limit the detection of Earth-twins using Doppler spectroscopy. Such stellar noise...

Polarimetric calibration of large mirrors

Aims: To propose a method for the polarimetric calibration of large astronomical mirrors that does not require use of special optical devices nor knowledge of the exact polarization properties of the...
