The Bochum Survey of the Southern Galactic Disk: III. Complete Data Release
Astronomische Nachrichten, Volume 347, Issue 3, March 2026.ABSTRACT The Southern Galactic Disk Survey (GDS) monitored a mosaic of 268 fields along a 6°$$ {6}^{{}^{\circ}} $$‐wide stripe in the southern Galactic disk with simultaneous observations in r′$$ {r}^{\prime } $$ and i′$$ {i}^{\prime } $$ (7m≲r′,i′≲18m$$ {7}^{\mathrm{m}}\lesssim {r}^{\prime },{i}^{\prime}\lesssim {18}^{\mathrm{m}} $$) from September ...

Reddening map and recent star formation in the Magellanic Clouds based on OGLE IV Cepheids
, 2019 Context. The reddening maps of the Large Magellanic Cloud (LMC) and Small Magellanic Cloud (SMC) are constructed using the Cepheid period–luminosity (P–L) relations. Aims.

The Astronomical JournalThe viability of the star count (Wolf) method is assessed as a means of constraining the near-infrared (NIR) extinction law toward the Corona Australis molecular cloud. Using deep JHK _S photometry from the VISIONS survey, extinction maps with 1′ spatial

Critical Slowing Down Reveals Hydrologic Resilience Loss Across Amazon Sub‐Basins
Water Resources Research, Volume 62, Issue 3, March 2026.Abstract The Amazon's hydroclimate exhibits basin‐scale early‐warning signals of critical slowing down (CSD), a statistical signature of declining resilience as systems approach critical transitions. We apply a multi‐metric framework to precipitation, evapotranspiration, Soil moisture (SM), and extreme streamflows, tracking rolling variance, lag‐1 ...

Formation Process of the Young Stellar Population in Messier 16 from a Kinematic Perspective
The Astronomical JournalWe present a kinematic study of young stars in Messier 16 (M16) using the Gaia Data Release 3 and high-resolution spectra. A total of 345 stars are selected as genuine members using the published lists of X-ray sources, infrared sources, and early-type ...

Cepheid Metallicity in the Leavitt Law (C–MetaLL) survey
Astronomy & AstrophysicsContext. The C-MetaLL project has provided homogeneous spectroscopic abundances of 290 Classical Cepheids (DCEPs) for which we have the intensity-averaged magnitudes in multiple optical and NIR bands, periods, pulsation modes, and Gaia parallaxes ...

Question the Mark: A Review and Assessment of Bat Marking Practices
Mammal Review, Volume 56, Issue 1, March 2026.We reviewed a decade of research on bats and conducted a broader systematic review to assess the nature of bat marking practices and the effects and efficacy of marks. Effects of marks on bats, mark details and marking procedures are rarely reported and further research on the effects of marks on bats and more thorough reporting are needed.

The Reddening Law of Galaxy Cluster Dust
, 2007 Dust is expected to enter the intracluster medium in galaxy clusters both through stripping of galactic interstellar matter and through dusty winds from intracluster stars.

Near-infrared reddening of extra-galactic giant molecular clouds in a face-on geometry
, 2008 Aims. We describe the near-infrared reddening signature of giant molecular clouds (GMCs) in external galaxies. In particular, we examine the EJ-H and $ E_{H-K}$ color excesses and the effective extinction law observed in discrete GMC regions.

The Astronomical JournalThe extinction law from ultraviolet (UV) to infrared (IR; 0.2–24 μ m) is determined by relying on the blue-edge method and color-excess ratios for some nearby molecular clouds, from the low-mass star-forming region to the massive star-forming region. The
