Astronomy Job Crisis
Astronomers in CANDELS outline changes for the academic system to promote a smooth transition for junior scientists from academia to industry.
View ArticleStatus of the DAMIC direct dark matter search experiment [Replacement]
The DAMIC experiment uses fully depleted, high resistivity CCDs to search for dark matter particles. With an energy threshold $\sim$50 eV$_{ee}$, and excellent energy and spatial resolutions, the DAMIC...
View ArticleDebris Engine: A Potential Thruster for Space Debris Removal [Replacement]
We present a design concept for a space engine that can continuously remove the orbit debris by using the debris as a propellant. Space robotic cleaner is adopted to capture the targeting debris and to...
View ArticleOn the universality of interstellar filaments: theory meets simulations and...
Filaments are ubiquitous in the universe. Recent observations have revealed that stars and star clusters form preferentially along dense filaments. Understanding the formation and properties of...
View ArticleThe Mid-Infrared Instrument for the James Webb Space Telescope: IV. The Low...
The Low Resolution Spectrometer of the MIRI, which forms part of the imager module, will provide R~100 long-slit and slitless spectroscopy from 5 to 12 micron. The design is optimised for observations...

We present the upGREAT THz heterodyne arrays for far-infrared astronomy. The Low Frequency Array (LFA) is designed to cover the 1.9-2.5 THz range using 2x7-pixel waveguide-based HEB mixer arrays in a...
View ArticleLow-latency analysis pipeline for compact binary coalescences in the advanced...
The Multi-Band Template Analysis (MBTA) pipeline is a low-latency coincident analysis pipeline for the detection of gravitational waves (GWs) from compact binary coalescences (CBCs). MBTA runs with a...
View ArticleCalibration of Gamma-ray Burst Polarimeter POLAR
Gamma Ray Bursts (GRBs) are the strongest explosions in the universe which might be associated with creation of black holes. Magnetic field structure and burst dynamics may influence polarization of...

The Multi-Band Template Analysis (MBTA) pipeline is a low-latency coincident analysis pipeline for the detection of gravitational waves (GWs) from compact binary coalescences (CBCs). MBTA runs with a...
View ArticleA pilot ASKAP survey of radio transient events in the region around the...
We use observations from the Boolardy Engineering Test Array (BETA) of the Australian Square Kilometre Array Pathfinder (ASKAP) telescope to search for transient radio sources in the field around the...
View ArticleTerahertz Coded Aperture Mask using a Vanadium Dioxide Bowtie Antenna Array...
Terahertz imaging systems have received substantial attention from the scientific community for their use in astronomy, spectroscopy, plasma diagnostics and security. One approach to designing such...
View ArticleDecontaminating Swift UVOT Grism Observations of Transient Sources
We present a new technique of decontaminating Swift UVOT grism spectra for transient objects. We describe the template image requirements and image processing steps necessary to successfully implement...
View ArticleComplete determination of the orbital parameters of a system with N+1 bodies...
Here we show how to determine the orbital parameters of a system composed of a star and N companions (that can be planets, brown-dwarfs or other stars), using a simple Fourier analysis of the radial...
View ArticleDynamic spectral mapping of interstellar plasma lenses
Compact radio sources sometimes exhibit intervals of large, rapid changes in their flux-density, due to lensing by interstellar plasma crossing the line-of-sight. A novel survey program has made it...
View ArticleThe Reflecting Heliometer of Rio de Janeiro after 6 Years of Activity
Started its regular, daily operational phase in 2011 and installed in 2009 by the occasion of the Symp264 in the XXVII IAU GA at Rio de Janeiro, the results so far obtained show that the Heliometer of...
View ArticleMulti-Object Spectroscopy with MUSE
Since 2014, MUSE, the Multi-Unit Spectroscopic Explorer, is in operation at the ESO-VLT. It combines a superb spatial sampling with a large wavelength coverage. By design, MUSE is an integral-field...
View ArticleThe SVOM gamma-ray burst mission
We briefly present the science capabilities, the instruments, the operations, and the expected performance of the SVOM mission. SVOM (Space-based multiband astronomical Variable Objects Monitor) is a...
View ArticleThe JScanam Map-Maker Method Applied to Herschel/PACS Photometer Observations
JScanam is the default map-maker for Herschel/PACS photometer observations. Making use of the redundant information from multiple passages on the sky with different scanning directions, JScanam is able...
View ArticleSealed operation, and circulation and purification of gas in the HARPO TPC...
HARPO is a time projection chamber (TPC) demonstrator of a gamma-ray telescope and polarimeter in the MeV-GeV range, for a future space mission. We present the evolution of the TPC performance over a...
View ArticleStatic Multiresolution Grids with Inline Hierarchy Information
For numerical simulations of cosmic-ray propagation fast access to static magnetic field data is required. We present a data structure for multiresolution vector grids, which are optimized for fast...
