Origin of the King's Trough Complex (North Atlantic): Interplay Between a Transient Plate Boundary and the Early Azores Mantle Plume

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 12, December 2025.
Abstract The King's Trough cuts into an area of thickened oceanic crust associated with the 45°N melting anomaly at the Mid‐Atlantic Ridge. Here we present a comprehensive geochemical data set and new 40Ar/39Ar age and bathymetric data from magmatic rocks from the King's Trough and the smaller Peake and Freen Deeps to the east and from the Gnitsevich ...

Near-infrared photometry of globular clusters towards the Galactic bulge: observations and photometric metallicity indicators [PDF]

, 2016
We present wide field JHKs photometry of 16 Galactic globular clusters located towards the Galactic bulge, calibrated on the 2MASS photometric system. Differential reddening corrections and statistical field star decontamination are employed for all of ...

Composition of Giants 1° North of the Galactic Center: Detailed Abundance Trends for 21 Elements Observed with IGRINS

The Astrophysical Journal
We report the first high-resolution, detailed abundances of 21 elements for giants in the Galactic bulge/bar within 1° of the Galactic plane, where high extinction has rendered such studies challenging. Our high-signal-to-noise-ratio and high-resolution,

An Attempt to Detect the Galactic Bulge at 12 microns with IRAS

, 1998
Surface brightness maps at 12 microns, derived from observations with the Infrared Astronomical Satellite (IRAS), are used to estimate the integrated flux at this wavelength from the Galactic bulge as a function of galactic latitude along the minor axis.

Stormtime Magnetospheric Processes Associated With the Dawnside Current Wedge

Journal of Geophysical Research: Space Physics, Volume 130, Issue 12, December 2025.
Abstract The intensification of the westward auroral electrojet (AEJ) in the dawn sector is a characteristic feature of the storm main phase. It is considered an ionospheric segment of a wedge‐type current system, the dawnside current wedge (DCW), formed by the disruption (short‐circuiting through the ionosphere) of a magnetospheric equatorial current.

A Near-infrared Extinction and Reddening Map toward the Galactic Bulge Using UKIRT

The Astronomical Journal
The Galactic bulge is one of the most information-dense regions to study resolved stellar populations, variables, and transients, such as microlensing events.

Blazhko modulation in first-overtone RR Lyrae stars from the OGLE Collection

EPJ Web of Conferences, 2017
We present results of the first comprehensive study of the Blazhko effect in first-overtone RR Lyrae stars from the Galactic bulge based on the Optical Gravitational Lensing Experiment data.

Reddening and Extinction Toward the Galactic Bulge from OGLE-III: The Inner Milky Way's Rv ~ 2.5 Extinction Curve [PDF]

, 2013
We combine VI photometry from OGLE-III with VVV and 2MASS measurements of E(J-K_{s}) to resolve the longstanding problem of the non-standard optical extinction toward the Galactic bulge.

3D Petro‐Structural Evolution of the High Pressure‐Low Temperature Phyllite‐Quartzite Nappe Pile in Southern Peloponnese, Greece

Tectonics, Volume 44, Issue 12, December 2025.
Abstract Tectonic underplating of high‐pressure/low‐temperature (HP‐LT) tectonic slices is a key mechanism in crustal growth at convergent margins. Yet, the processes controlling the geometry, depth and sequence of underplating events remain poorly constrained.
