Radiation drag driven mass accretion in clumpy interstellar medium: implications for the supermassive black hole-to-bulge relation [PDF]

open access: yes, 2001
We quantitatively scrutinize the effects of the radiation drag arising from the radiation fields in a galactic bulge in order to examine the possibility that the radiation drag could be an effective mechanism to extract angular momentum in a spheroidal ...

Advances in Topological Thermoelectrics: Harnessing Quantum Materials for Energy Applications

open access: yesAdvanced Materials, Volume 37, Issue 39, October 2, 2025.
Topological materials offer a novel platform for thermoelectric energy conversion through unique band features, including band inversion, linear Dirac bands, surface states, and Berry curvature. These quantum characteristics enable enhanced longitudinal and transverse thermoelectric effects, establishing topological thermoelectrics as a promising ...

Lundisim: Model Meshes for Flow Simulation and Scientific Data Compression Benchmarks

open access: yesGeoscience Data Journal, Volume 12, Issue 4, October 2025.
Increasing scientific data sizes impact computability, interpretability, and sustainability. For a comprehensive evaluation of compression performance and modelling challenges, we highlight five issues (efficiency, discrepancy, diversity, interpretability, availability) and provide LUNDIsim, FAIR open data model meshes for flow simulation in porous ...

Nucleosynthesis of Cobalt and Copper

open access: yesGalaxies
Chemical abundances of cobalt (Co; Z = 27) and copper (Cu; Z = 29) in bulge and halo stars are presented and compared with chemical evolution models.

Kinematics of the X-shaped Milky Way Bulge: Expectations from a Self-consistent N-body Model

open access: yes, 2015
We explore the kinematics (both the radial velocity and the proper motion) of the vertical X-shaped feature in the Milky Way with an N-body bar/bulge model.

Dark Atoms and the Positron-Annihilation-Line Excess in the Galactic Bulge

open access: yesAdvances in High Energy Physics, 2014
It was recently proposed that stable particles of charge −2, O--, can exist and constitute dark matter after they bind with primordial helium in O-helium (OHe) atoms.

SPI observations of positron annihilation radiation from the 4th galactic quadrant: sky distribution

open access: yes, 2004
During its first year in orbit the INTEGRAL observatory performed deep exposures of the Galactic Center region and scanning observations of the Galactic plane.

Einstein@Home Searches for Gamma-Ray Pulsars in the Inner Galaxy

open access: yesThe Astrophysical Journal
The Fermi Large Area Telescope (LAT) has revealed a mysterious extended excess of GeV gamma-ray emission around the Galactic Center (GC), which can potentially be explained by unresolved emission from a population of pulsars, particularly millisecond ...
