Long-term Simultaneous Monitoring Observations of SiO and H2O Masers toward the Mira Variable WX Serpentis

open access: yesThe Astrophysical Journal Supplement Series
We present the results from long-term simultaneous monitoring observations of SiO and H _2 O masers toward the Mira variable star WX Serpentis. This study has been conducted with 21 m single-dish radio telescopes of the Korean VLBI Network from 2009 June

Fungal Diversity and Potential Health Benefits of Mycophagy in Chacma Baboons (Papio ursinus)

open access: yesAmerican Journal of Primatology, Volume 88, Issue 4, April 2026.
Free‐ranging chacma baboons (Papio ursinus) in Nature's Valley, South Africa, of multiple age/sex classes eat diverse fungi (10 identified to species level, 3 to genus level). We assess potential nutritional, medicinal and ecosystem implications of consumption of these fungi based on human and other mammalian mycophagy literature.

The extraordinary outburst in the massive protostellar system NGC 6334I-MM1: flaring of the water masers in a north-south bipolar outflow driven by MM1B [PDF]

open access: yes, 2018
We compare multi-epoch sub-arcsecond Very Large Array imaging of the 22 GHz water masers toward the massive protocluster NGC 6334I observed before and after the recent outburst of MM1B in (sub)millimeter continuum.

Radio Continuum and Water Maser Observations of the High-mass Protostar IRAS 19035+0641 A

open access: yesThe Astrophysical Journal
We present Very Large Array 1.3 cm continuum and 22.2 GHz H _2 O maser observations of the high-mass protostellar object IRAS 19035+0641 A. Our observations unveil an elongated bipolar 1.3 cm continuum structure at scales ≲500 au, which, together with a ...

A cloud collision model for water maser excitation

open access: yesThe Astrophysical Journal, 1986
High-velocity collisions between small, dense, neutral clouds or between a dense cloud and a dense shell can provide the energy source required to excite H2O maser emission. The radiative precursor from the surface of the collisional shock front rapidly diffuses through the cloud, heating the dust grains but leaving the H2 molecules cool.

Using multilayer socioecological networks to assess ecosystem service flow in a subsistence farming community in Papua New Guinea

open access: yesPeople and Nature, Volume 8, Issue 4, Page 854-870, April 2026.
Abstract Ecosystem services are rapidly degrading under anthropogenic pressure. Therefore, it is increasingly important to understand how ecosystem services flow, particularly at local scales, where people directly rely on nature for their livelihoods and well‐being. Many ecosystem services are underpinned by ecological (e.g.

Water masers in the Local Group of galaxies

open access: yes, 2020
. We compare the number of detected 22 GHz H 2 O masers in the Local Group galaxies M31, M33, NGC 6822, IC 10, IC 1613, DDO 187, GR8, NGC 185, and the Magellanic Clouds with the water maser population of the Milky Way.

Radio Continuum and Water Maser Monitoring of the Outburst in HOPS 373: Free–Free Emission Does Not Respond to the Outburst

open access: yesThe Astronomical Journal
We present Very Large Array (VLA) C -band (5 cm) continuum, K -band (1.3 cm) continuum, and water maser (22.235 GHz) monitoring of the protostar HOPS 373. We additionally present the contemporaneous monitoring for 95 sources within the 5 cm field of view

Frequency Extensions of Auroral Kilometric Radiation: The Key to Unlocking Earth's Radio Response to Substorms

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.
Abstract Auroral kilometric radiation (AKR) provides a sensitive probe of magnetospheric dynamics during substorms. We analyze an extended data set of AKR bursts observed by the WIND spacecraft to investigate how the frequency structure of AKR responds to substorm onset and evolution.

An Outflow-driven Water Maser Associated with Positive Black Hole Feedback in the Dwarf Galaxy Henize 2–10

open access: yesThe Astrophysical Journal
Henize 2–10 is a dwarf galaxy experiencing positive black hole (BH) feedback from a radio-detected low-luminosity active galactic nucleus. Previous Green Bank Telescope (GBT) observations detected a H _2 O “kilomaser” in Henize 2–10, but the low angular ...
