A fast tree-based method for estimating column densities in Adaptive Mesh Refinement codes Influence of UV radiation field on the structure of molecular clouds
Valeska Valdivia, Patrick Hennebelle
Context. Ultraviolet radiation plays a crucial role in molecular clouds. Radiation and matter are tightly coupled and their interplay influences the physical and chemical propertie…
Autonomous Gaussian Decomposition
Robert R. Lindner, Carlos Vera-Ciro, Claire E. Murray +6
We present a new algorithm, named Autonomous Gaussian Decomposition (AGD), for automatically decomposing spectra into Gaussian components. AGD uses derivative spectroscopy and mach…
The NIKA 2012-2014 observing campaigns: control of systematic effects and results
A. Catalano, R. Adam, A. Adane +35
The New IRAM KID Array (NIKA) is a dual-band camera operating with frequency multiplexed arrays of Lumped Element Kinetic Inductance Detectors (LEKIDs) cooled to 100 mK. NIKA is de…
A Bayesian blind survey for cold molecular gas in the Universe
Lindley Lentati, Chris Carilli, Paul Alexander +2
A new Bayesian method for performing an image domain search for line-emitting galaxies is presented. The method uses both spatial and spectral information to robustly determine the…
HARPO: a TPC as a gamma-ray telescope and polarimeter
Denis Bernard, Philippe Bruel, Mickael Frotin +14
A gas Time Projection Chamber can be used for gamma-ray astronomy with excellent angular-precision and sensitivity to faint sources, and for polarimetry, through the measurement of…
UVMag: Space UV and visible spectropolarimetry
Martin Pertenais, Coralie Neiner, Laurent Pares +3
UVMag is a project of a space mission equipped with a high-resolution spectropolarimeter working in the UV and visible range. This M-size mission will be proposed to ESA at its M4…
Updated optical design and trade-off study for MOONS, the Multi-Object Optical and Near Infrared spectrometer for the VLT
E. Oliva, S. Todd, M. Cirasuolo +13
This paper presents the latest optical design for the MOONS triple-arm spectrographs. MOONS will be a Multi-Object Optical and Near-infrared Spectrograph and will be installed on o…
Gemini Planet Imager Observational Calibrations II: Detector Performance and Calibration
Patrick Ingraham, Marshall D. Perrin, Naru Sadakuni +7
The Gemini Planet Imager is a newly commissioned facility instrument designed to measure the near-infrared spectra of young extrasolar planets in the solar neighborhood and obtain…
Fundamental limitations of high contrast imaging set by small sample statistics
Dimitri Mawet, Julien Milli, Zahed Wahhaj +9
In this paper, we review the impact of small sample statistics on detection thresholds and corresponding confidence levels (CLs) in high contrast imaging at small angles. When look…
Comparison of fringe-tracking algorithms for single-mode near-infrared long-baseline interferometers
Élodie Choquet, Jonathan Menu, Guy Perrin +3
To enable optical long baseline interferometry toward faint objects, long integrations are necessary despite atmospheric turbulence. Fringe trackers are needed to stabilize the fri…
Analysis of on-sky MOAO performance of CANARY using natural guide stars
Fabrice Vidal, Eric Gendron, Gerard Rousset +13
The first on-sky results obtained by CANARY, the Multi-Object Adaptive Optics (MOAO) demonstrator, are analysed. The data were recorded at the William Herschel Telescope, at the en…
