Aircraft surveys for air eDNA: probing biodiversity in the sky [PDF]
PeerJ, 2023 Air is a medium for dispersal of environmental DNA (eDNA) carried in bioaerosols, yet the atmosphere is mostly unexplored as a source of genetic material encompassing all domains of life.

Proceedings of The many facets of extragalactic radio surveys: towards new scientific challenges — PoS(EXTRA-RADSUR2015), 2016 The VLA All-Sky Survey (VLASS) builds upon the newly upgraded Karl G. Jansky Very Large Array (VLA) to employ its enhanced bandwidth, time resolution, and survey speed to carry out a next-generation sky survey. VLASS will map the sky at δ > −40°, covering a total of 33,885 square degrees, with 2.005 angular resolution using the VLA B-array at 2–4

Verification of Photometric Parallaxes with Gaia DR2 Data
Galaxies, 2018 Results of comparison of Gaia DR2 parallaxes with data derived from a combined analysis of 2MASS (Two Micron All-Sky Survey), SDSS (Sloan Digital Sky Survey), GALEX (Galaxy Evolution Explorer), and UKIDSS (UKIRT Infrared Deep Sky Survey) surveys in four ...

Symposium - International Astronomical Union, 1997 Among all spectral bands, the ultraviolet has long been neglected, despite the advantage of small space experiments: the sky is very dark, thus detection of faint objects does not compete against an enhanced background (O'Connell 1987) and the telescope construction techniques are very similar (at least longward of ∼50 nm) to those of optical astronomy.

INFRARED AND HARD X-RAY DIAGNOSTICS OF ACTIVE GALACTIC NUCLEUS IDENTIFICATION FROM THE SWIFT/BAT AND AKARI ALL-SKY SURVEYS [PDF]
, 2012 We combine data from two all-sky surveys in order to study the connection between the infrared and hard X-ray (>10 keV) properties for local active galactic nuclei (AGNs).

Hunting Gamma-Ray-emitting FR0 Radio Galaxies in Wide-field Sky Surveys
The Astrophysical Journal, 2023 The latest entry in the jetted active galactic nuclei (AGN) family is the Fanaroff–Riley type 0 (FR0) radio galaxies. They share several observational characteristics, e.g., nuclear emission and host galaxy morphology, with FR I sources; however, they ...

The ultraviolet sky: An overview from the GALEX surveys [PDF]
, 2013 The Galaxy Evolution Explorer (GALEX) has performed the first surveys of the sky in the ultraviolet (UV). Its legacy is an unprecedented database with more than 200 million source measurements in far-UV (FUV) and near-UV (NUV), as well as wide-field ...

The Zwicky Transient Facility: Surveys and Scheduler [PDF]
Publications of the Astronomical Society of the Pacific, 2019 We present a novel algorithm for scheduling the observations of time-domain imaging surveys. Our integer linear programming approach optimizes an observing plan for an entire night by assigning targets to temporal blocks, enabling strict control of the ...

calclens: weak lensing simulations for large-area sky surveys and second-order effects in cosmic shear power spectra [PDF]
, 2012 I present a new algorithm, CALCLENS, for efficiently computing weak gravitational lensing shear signals from large N-body light cone simulations over a curved sky.

The Dark Energy Camera Plane Survey 2 (DECaPS2): More Sky, Less Bias, and Better Uncertainties
The Astrophysical Journal Supplement Series, 2023 Deep optical and near-infrared imaging of the entire Galactic plane is essential for understanding our Galaxy’s stars, gas, and dust. The second data release of the Dark Energy Camera (DECam) Plane Survey extends the five-band optical and near-infrared ...
