New Conceptional Study of a Portable Highly Sensitive Photometric Raman Sensor
Sensors, 2022 Quality control and reaction monitoring are necessary to ensure the consistency of any kind of mixing or reaction process. In this context, a novel portable high-sensitivity sensor prototype based on the Raman effect is presented in this study.

Galactic reddening in 3D from stellar photometry – an improved map [PDF]
, 2018 We present a new 3D map of interstellar dust reddening, covering three quarters of the sky (declinations of δ ≳ −30°) out to a distance of several kiloparsecs. The map is based on high-quality stellar photometry of 800 million stars from Pan-STARRS 1 and

Massive Stars as the Radiant Queens of the Universe—The Case of ζ Puppis
Universe, 2022 Since the Cosmic Dawn, massive stars have been playing a crucial role as the chemical recycling engines of galaxies that enable the birth of new stars and planetary systems, not only through the strong winds that they exhibit during their relatively ...

Photometry as a Proxy for Stellar Activity in Radial Velocity Analyses [PDF]
Astronomical Journal, 2020 Stellar activity remains a limiting factor in measuring precise planet parameters from radial velocity spectroscopy, not least in the search for Earth-mass planets orbiting in the habitable zones of Sun-like stars.
