Polygon‐Based Spectral Reflectance Sampling for Real‐Time River Discharge Estimation
Water Resources Research, Volume 62, Issue 9, September 2026.Abstract River discharge estimation (RDE) methods are traditionally prone to high costs, vulnerability to extreme events, and are constrained by real‐time data availability. Current remote sensing‐based RDE approaches mainly extract basic river features such as width and water surface elevation, but rarely exploit the full spectral information from ...

Infrared fibres in astronomical instrumentation [PDF]
, 1995 For several years multi-object spectroscopy systems have been available for carrying out survey work in the visible region, but until very recently there has not been a system for the near infrared region.

Dust-obscured Galaxies with Broken Power-law Spectral Energy Distributions Discovered by UNIONS
The Astrophysical JournalWe report on the spectral energy distributions (SEDs) of infrared (IR)-bright dust-obscured galaxies (DOGs) with ( i − [22]) _AB ≥ 7.0. Using photometry from the deep and wide Ultraviolet Near-Infrared Optical Northern Survey, combined with near-IR (NIR)

FIR/Submm Spectroscopy with Herschel: First Results from the VNGS and H-Atlas Surveys
Open Astronomy, 2011 The FIR/submm window is one of the least-studied regions of the electromagnetic spectrum, yet this wavelength range is absolutely crucial for understanding the physical processes and properties of the ISM in galaxies.

Mid-infrared Ensemble Variability of Broad-line and Narrow-line Seyfert 1 Galaxies
The Astrophysical JournalWe utilized multiepoch archival data from the Wide-field Infrared Survey Explorer to compare the variability at 3.4 μ m (W1 band) and 4.6 μ m (W2 band) of broad-line Seyfert 1 (BLSy1) galaxies and narrow-line Seyfert 1 (NLSy1) galaxies by employing the ...

The far-infrared/submillimeter properties of galaxies located behind the Bullet cluster* [PDF]
, 2010 The Herschel Lensing Survey (HLS) takes advantage of gravitational lensing by massive galaxy clusters to sample a population of high-redshift galaxies which are too faint to be detected above the confusion limit of current far-infrared/submillimeter ...

Line-strength indices and velocity dispersions for 148 early-type galaxies in different environments [PDF]
, 2002 We have derived high quality line-strength indices and velocity dispersions for a sample of 148 early-type galaxies in different environments. The wavelength region covered by the observations ($\lambda \simeq 4600$ to 6600 Å) includes the Lick/IDS ...
