Sloan Digital Sky Survey-V: Pioneering Panoptic Spectroscopy
Juna A. Kollmeier, Hans-Walter Rix, Conny Aerts +217
The Sloan Digital Sky Survey-V (SDSS-V) is pioneering panoptic spectroscopy: it is the first all-sky, multi-epoch, optical-to-infrared spectroscopic survey. SDSS-V is mapping the s…
Fast interactive web-based data visualizer of panoramic spectroscopic surveys
Ivan Katkov, Damir Gasymov, Joseph D. Gelfand +7
Panoramic IFU spectroscopy is a core tool of modern observational astronomy and is especially important for galaxy physics. Many massive IFU surveys, such as SDSS MaNGA (10k target…

RCSEDv2: analytic approximations of k-corrections for galaxies out to redshift
Anastasia Kasparova, Igor Chilingarian, Sviatoslav Borisov +6
To compare photometric properties of galaxies at different redshifts, we need to correct fluxes for the change of effective rest-frame wavelengths of filter bandpasses, called -…
Hybrid minimization algorithm for computationally expensive multi-dimensional fitting
Evgenii Rubtsov, Igor Chilingarian, Ivan Katkov +3
Multi-dimensional optimization is widely used in virtually all areas of modern astrophysics. However, it is often too computationally expensive to evaluate a model on-the-fly. Typi…
Multi-segment and Echelle stellar spectra processing issues and how to solve them
Sviatoslav Borisov, Igor Chilingarian, Evgenii Rubtsov +7
High-quality stellar spectra are in great demand now - they are the most important ingredient in the stellar population synthesis to study galaxies and star clusters. Here we descr…
