The Antarctic Marginal Ice Zone and Pack Ice Area in CMEMS GREP Ensemble Reanalysis Product

open access: yesFrontiers in Earth Science, 2022
Global ocean reanalyses provide consistent and comprehensive records of ocean and sea ice variables and are therefore of pivotal significance for climate studies, particularly in data-sparse regions such as Antarctica.

Revision of WDM7 Microphysics Scheme and Evaluation for Precipitating Convection over the Korean Peninsula

open access: yesRemote Sensing, 2021
The Weather Research and Forecasting (WRF) Double-Moment 7-Class (WDM7) cloud microphysics scheme was developed to parameterize cloud and precipitation processes explicitly for mesoscale phenomena in the Korean Integrated Model system.

Kepler Bonus: Light Curves of Kepler Background Sources

open access: yesThe Astronomical Journal, 2023
NASA’s Kepler primary mission observed about 116 deg ^2 in the sky for 3.5 consecutive years to discover Earth-like exoplanets. This mission recorded pixel cutouts, known as target pixel files (TPFs), of over 200,000 targets that were selected to ...

Autoencoding Galaxy Spectra. I. Architecture

open access: yesThe Astronomical Journal, 2023
We introduce the neural network architecture spender as a core differentiable building block for analyzing, representing, and creating galaxy spectra. It combines a convolutional encoder, which pays attention to up to 256 spectral features and compresses

Deep Learning of Quasar Lightcurves in the LSST Era

open access: yesUniverse, 2023
Deep learning techniques are required for the analysis of synoptic (multi-band and multi-epoch) light curves in massive data of quasars, as expected from the Vera C. Rubin Observatory Legacy Survey of Space and Time (LSST).

Joint Modeling of Radial Velocities and Photometry with a Gaussian Process Framework

open access: yesThe Astrophysical Journal, 2023
Developments in the stability of modern spectrographs have led to extremely precise instrumental radial velocity (RV) measurements. For most stars, the detection limit of planetary companions with these instruments is expected to be dominated by ...

HAFFET: Hybrid Analytic Flux FittEr for Transients

open access: yesThe Astrophysical Journal Supplement Series, 2023
The progenitors for many types of supernovae (SNe) are still unknown, and an approach to diagnose their physical origins is to investigate the light-curve brightness and shape of a large set of SNe.

Cryogenic MMIC low noise amplifiers [PDF]

open access: yes, 2000
Monolithic (MMIC) and discrete transistor (MIC) low noise amplifiers are compared on the basis of performance, cost, and reliability. The need for cryogenic LNA’s for future large microwave arrays for radio astronomy is briefly discussed and data is ...
