, 2011 We present new maser emission from ^{14}NH_3 (9,6) in NGC 7538. Our observations include the known spectral features near v_LSR = -60 km/s and -57 km/s and several more features extending to -46 km/s. In three epochs of observation spanning two months we

Ecology and Evolution, Volume 15, Issue 8, August 2025.This meta‐analysis on intraspecific variation in European trees studied the frequency of provenance variation, provenance–environment interaction, clinal variation along the climate of origin or transfer distance. While identifying trait group specific patterns of variation, research gaps have been identified in terms of age and geographical ...

Properties of H2O Masers and Their Associated Sources in Sagittarius B2
The Astrophysical JournalWe present high-resolution Karl G. Jansky Very Large Array observations of the 22 GHz H _2 O maser line in the extended Sagittarius B2 cloud. We detect 499 H _2 O masers across the observed velocities between −39 and 172 km s ^−1 .

OH main line masers in the M82 starburst
, 2007 A study of the distribution of OH gas in the central region of the nearby active starburst galaxy M82 has confirmed two previously known bright masers and revealed several new main line masers.

OH 12.8-0.9: A New Water-Fountain Source
, 2005 We present observational evidence that the OH/IR star OH 12.8-0.9 is the fourth in a class of objects previously dubbed "water-fountain" sources. Using the Very Long Baseline Array, we produced the first images of the water maser emission associated with

Water maser detections in southern candidates to post-AGB stars and Planetary Nebulae
, 2009 We intended to study the incidence and characteristics of water masers in the envelopes of stars in the post-AGB and PN evolutionary stages. We have used the 64-m antenna in Parkes (Australia) to search for water maser emission at 22 GHz, towards a ...

The structure of the magnetic field in the massive star-forming region W75N
, 2011 A debated topic in star formation theory is the role of magnetic fields during the protostellar phase of high-mass stars. It is still unclear how magnetic fields influence the formation and dynamics of massive disks and outflows. Most current information

Water maser emission in planetary nebulae
, 2011 Planetary Nebulae (PNe) evolve from Asymptotic Giant Branch (AGB) stars after a brief post-AGB phase. Water maser emission is characteristic of oxygen-rich AGB stars, is observed in post-AGB stars and, unexpectedly, has been detected in three PNe (IRAS17347-3139, IRAS18061-2505 and IRAS19255+2123) where the physical conditions to generate water maser ...
