Geochemistry, Geophysics, Geosystems, Volume 27, Issue 3, March 2026.Abstract Two sediment cores were collected from a submarine sediment wave field on the flank of Macauley volcano. Combined with seismic reflection surveys and numerical modeling, we present an integrated model of the formation of large‐scale, eruption‐fed, submarine sediment waves. The sediment waves are large (>100 m high, 1.5 km wide, tens of km long)

Dynamics of the galactic bulge-bar
AIP Conference Proceedings, 1992 The non‐circular velocities of gas in the inner few degrees of our Galaxy would arise naturally if the Milky Way had a small bar at its center. Recent studies suggest that this bar is more rapidly rotating than had been previously suggested; corotation probably lies near R=2.4 kpc. The circular speed associated with the Galaxy’s monopole component must

The Astrophysical Journal Supplement SeriesThis work is part of VESTALE, a project initiated within the Legacy Survey of Space and Time (LSST) Cadence Strategy Optimization Process. Its goal is to explore the potential of Rubin-LSST observations aimed at the Galactic bulge (henceforth just “Bulge”

Probing MACHOs toward the Galactic Bulge [PDF]
The Astrophysical Journal, 2005 If the massive compact halo object (MACHO) fraction of the Galactic dark halo is f ~ 20% as suggested by some microlensing experiments, then about 1.2% of lensing events toward the Galactic bulge are due to MACHOs. For the 40% of these that lie nearby (D_l < 4 kpc), measurement of their distance D_l would distinguish them from bulge lenses, while ...

Classification of OGLE Variables in Galactic Bulge [PDF]
Journal of Astronomy and Space Sciences, 1997 The miscellaneous variables observed by OGLE Project of searching for dark matter in our Galaxy have been analyzed to find their characteristics. We investigated evolutionary status, shape of light curve, relationship between orbital period and amplitude

The sky distribution of 511 keV positron annihilation line emission as measured with INTEGRAL/SPI [PDF]
, 2007 The imaging spectrometer SPI on board ESA's INTEGRAL observatory provides us with an unprecedented view of positron annihilation in our Galaxy. The first sky maps in the 511 keV annihilation line and in the positronium continuum from SPI showed a ...

Probing the Galactic Bulge with deep Adaptive Optics imaging: the age of NGC 6440
, 2008 We present first results of a pilot project aimed at exploiting the potentiality of ground based adaptive optics imaging in the near infrared to determine the age of stellar clusters in the Galactic Bulge.
