New Light on Dark Extended Lenses with the Roman Space Telescope

The Astrophysical Journal Letters
The Roman Space Telescope’s Galactic Bulge Time Domain Survey will constitute the most sensitive microlensing survey of the Galactic bulge to date, opening up new opportunities to search for dark matter (DM). Many extensions of the Standard Model predict

Mantle Structure Beneath the Greater Alpine Region From Teleseismic Full P‐Waveform Inversion

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 11, November 2025.
Abstract AlpArray data were employed to infer a new mantle model of the Alps from teleseismic full P‐waveform inversion. It features hybrid numerical forward modeling in the time domain, compression of wavefields by Fourier transform at selected frequencies, the use of frequency domain waveform sensitivity kernels and a multi‐scale approach by ...

The Microlensing Event Rate and Optical Depth from MOA-II 9 Yr Survey Toward the Galactic Bulge

The Astrophysical Journal
We present measurements of the microlensing optical depth and event rate toward the Galactic bulge using the data set from the 2006 to 2014 MOA-II survey, which covers 22 bulge fields spanning ∼42 deg ^2 between −5°

First Detection of [SI] in Near‐IR JWST Observations of Io in Eclipse, and Comparison With SO Emissions, Evolving Volcanic Eruptions, and Prior UV HST‐STIS [SI] Emissions

Journal of Geophysical Research: Planets, Volume 130, Issue 11, November 2025.
Abstract We observed Io with the James Webb Space Telescope (JWST) NIRSpec/Integral Field Unit (1.0–5.3 μm, R∼2700 $R\sim 2700$) in August 2023 while the satellite was in eclipse. Thermal emission from Kanehekili Fluctus is consistent with the cooling of lava flows after a vigorous eruption in November 2022.

IS THE GALACTIC BULGE DEVOID OF PLANETS? [PDF]

, 2016
We consider a sample of 31 exoplanetary systems detected by gravitational microlensing and investigate whether or not the estimated distances to these systems conform to the Galactic distribution of planets expected from models.

Galactic orbits of globular clusters in the region of the Galactic bulge [PDF]

Astronomy reports (Print), 2017
Galactic orbits have been constructed over long time intervals for ten globular clusters located near the Galactic center. A model with an axially symmetric gravitational potential for the Galaxy was initially applied, after which a non-axially symmetric

The Optical Gravitational Lensing Experiment. Is Interstellar Extinction Toward the Galactic Center Anomalous?

, 2002
Photometry of the Galactic bulge, collected during the OGLE-II microlensing search, indicates high and non-uniform interstellar extinction toward the observed fields.

Tracing the Syn‐Convergence Extrusion Tectonics of the Sulu Orogenic Belt and Its Implication for North China–South China Collision

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 11, November 2025.
Abstract Understanding the transition from oceanic to continental subduction is critical for reconstructing the geodynamic evolution of orogens and constraining ancient plate boundaries. The Sulu orogenic belt in eastern China was formed by Triassic deep subduction of the South China Block (SCB) beneath the North China Block (NCB). Its architecture was

The EMBLA survey – metal-poor stars in the Galactic bulge [PDF]

, 2016
Cosmological models predict the oldest stars in the Galaxy should be found closest to the centre of the potential well, in the bulge. The Extremely Metal-poor BuLge stars with AAOmega survey (EMBLA) successfully searched for these old, metal-poor stars ...
