A water maser flare in W49N [PDF]

open access: yesAstronomy & Astrophysics, 2002
We report the results of our short time scale monitoring observations of W49N. Three water maser features were found to show obvious variations in flux density, line width and center velocity. Over a period of about 22 days, the -88.3, -56.9 and -12.8 km s(-1) features declined linearly in flux density at rates of 57, 113, 98.8 Jy per day, respectively.

Time variations of water masers [PDF]

open access: yesSymposium - International Astronomical Union, 2002
The strong water maser line at 22 GHz is an excellent tool for studying shocked and turbulent interstellar regions, especially, if simultaneous single-dish and VLBI data are available. After a brief review of 22 GHz time variation studies, we focus on effects caused by magnetic field pressure on observed properties of water masers.

5 cm OH Masers in Northern Star Formation Regions

open access: yesThe Astronomical Journal
We present a 6.0 GHz excited-state OH maser survey toward 155 northern star formation regions utilizing the Shanghai Tianma Radio Telescope. In total, we detect 44 6.0 GHz OH masers, 8 of which are new detections (one at 6016 MHz, two at 6030 MHz, and ...

Low Frequency Extensions of Cyclotron Maser Instability‐Generated Radio Emission: A Statistical View From Cassini at Saturn

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.
Abstract The Cassini spacecraft spent 13 years orbiting Saturn, quasi‐continuously measuring Saturn's radio emissions. One of the key elements of the radio spectrum at Saturn is the Saturn Kilometric Radiation (SKR), and several studies have been written on events called Low Frequency Extensions (LFEs) which represent strong, continuous extensions of ...

Excited-state OH Masers in the Water Fountain Source IRAS 18460-0151

open access: yesThe Astrophysical Journal Letters
Water fountain objects are generally defined as evolved stars with low to intermediate initial mass accompanied by high-velocity molecular jets detectable in the 22.235 GHz H _2 O maser line.

Penetration enhancement effects of topically applied crosslinked hyaluronic acid

open access: yesInternational Journal of Cosmetic Science, Volume 48, Issue 4, Page 798-812, August 2026.
Cross‐linked hyaluronic acid (HA) was demonstrated to enhance the topical delivery of a variety of hydrophilic actives into the skin. This phenomenon was observed for both small molecules and macromolecules, the latter of which was analysed with MALDI mass spectrometry imaging (MALDI‐MSI).
