All-fiber upconversion high spectral resolution wind lidar using a...
An all-fiber, micro-pulse and eye-safe high spectral resolution wind lidar (HSRWL) at 1550nm is proposed and demonstrated by using a pair of upconversion single-photon detectors and a fiber Fabry-Perot...
View ArticleProbing Ionospheric Structures using the LOFAR radio telescope
LOFAR is the LOw Frequency Radio interferometer ARray located at mid-latitude ($52^{\circ} 53'N$). Here, we present results on ionospheric structures derived from 29 LOFAR nighttime observations during...
View ArticleEvidence for periodicity in 43-year-long monitoring of NGC 5548
We present an analysis of 43 years (1972 to 2015) of spectroscopic observations of the Seyfert 1 galaxy NGC 5548. This includes 12 years of new unpublished observations (2003 to 2015). We compiled...
View ArticleSustaining educational and public outreach programs in astronomy [Cross-Listing]
We advocate meaningful support of sustained education-outreach partnerships between regional metropolitan undergraduate institutions and astronomical clubs and societies. We present our experience as...
View ArticleHigh sensitivity phonon-mediated kinetic inductance detector with combined...
The development of wide-area cryogenic light detectors with good energy resolution is one of the priorities of next generation bolometric experiments searching for rare interactions, as the...
View ArticleAn Algorithm for Real-Time Optimal Photocurrent Estimation including...
Mega-pixel charge-integrating detectors are common in near-IR imaging applications. Optimal signal-to-noise ratio estimates of the photocurrents, which are particularly important in the low-signal...

View ArticleRPC application in muography and specific developments [Replacement]
Muography is an imaging technique for large and dense structures as volcanoes or nuclear reactors using atmospheric muons. We applied this technique to the observation of the Puy de D\^ome, a volcano 2...
View ArticleGPz: Non-stationary sparse Gaussian processes for heteroscedastic uncertainty...
The next generation of cosmology experiments will be required to use photometric redshifts rather than spectroscopic redshifts. Obtaining accurate and well-characterized photometric redshift...
View ArticleStacking for machine learning redshifts applied to SDSS galaxies [Replacement]
We present an analysis of a general machine learning technique called 'stacking' for the estimation of photometric redshifts. Stacking techniques can feed the photometric redshift estimate, as output...
View ArticleZeemanfit: Use and Development of the solis_vms_zeemanfit code [Replacement]
The purpose of the SOLIS Zeemanfit Code is to provide a straight-forward, easily checked measure of the total magnetic-field strength in the high-strength umbral regions of the solar disk. In the...
View ArticleCalibration of weak-lensing shear in the Kilo-Degree Survey
We describe and test the pipeline used to measure the weak lensing shear signal from the Kilo Degree Survey (KiDS). It includes a novel method of `self-calibration' that partially corrects for the...
View ArticleLOLAS-2 : redesign of an optical turbulence profiler
We present the development, tests and first results of the second generation Low Layer Scidar (LOLAS-2). This instrument constitutes a strongly improved version of the prototype Low Layer Scidar, which...
View ArticleCharacterization of Three High Efficiency and Blue Sensitive Silicon...
We report about the optical and electrical characterization of three high efficiency and blue sensitive Silicon photomultipliers from FBK, Hamamatsu, and SensL. Key features of the tested devices when...
View ArticleDesign of the readout electronics for the DAMPE Silicon Tracker detector...
The Silicon Tracker (STK) is a detector of the DAMPE satellite to measure the incidence direction of high energy cosmic ray. It consists of 6 X-Y double layers of silicon micro-strip detectors with...
View ArticleSwift follow-up of gravitational wave triggers: results from the first aLIGO...
During its first observing run, in late 2015, the advanced LIGO facility announced 3 gravitational wave (GW) triggers to electromagnetic follow-up partners. Two of these have since been confirmed as...
View ArticleDetecting continuous gravitational waves with superfluid $^4$He [Cross-Listing]
Direct detection of gravitational waves is opening a new window onto our universe. Here, we study the sensitivity to continuous-wave strain fields of a kg-scale optomechanical system formed by the...
