Galactic halo cusp-core: tidal compression in mergers [PDF]

, 2002
We explain in simple terms how the buildup of dark haloes by merging compact satellites, as in the CDM cosmology, inevitably leads to an inner cusp of density profile $\rho \propto r^{-\alpha}$ with $\alpha \gsim 1$, as seen in cosmological N-body ...

Automated Mapping of Global 30-m Tidal Flats Using Time-Series Landsat Imagery: Algorithm and Products

Journal of Remote Sensing, 2023
Tidal flats are an important part of coastal ecosystems and play an important role in shoreline protection and biodiversity maintenance. Although many efforts have been made in tidal flat mapping, an accurate global tidal flat product covering all coasts

Energy Localization Invariance of Tidal Work in General Relativity [PDF]

, 2000
It is well known that, when an external general relativistic (electric-type) tidal field E(t) interacts with the evolving quadrupole moment I(t) of an isolated body, the tidal field does work on the body (``tidal work'') -- i.e., it transfers energy to ...

The hydrodynamics of the southern basin of Tauranga Harbour [PDF]

, 2013
The circulation of the southern basin of Tauranga Harbour was simulated using a 3-D hydrodynamic model ELCOM. A 9-day field campaign in 1999 provided data on current velocity, temperature and salinity profiles at three stations within the main basin. The

Mapping Tidal Flats of the Bohai and Yellow Seas Using Time Series Sentinel-2 Images and Google Earth Engine

Remote Sensing, 2022
Tidal flats are one of the most productive ecosystems on Earth, providing essential ecological and economical services. Because of the increasing anthropogenic interruption and sea level rise, tidal flats are under great threat.

The Dataset of Sedimentary Environments at Hwangdo Tidal Flat on the Western Coast of Korea (2004 to 2013) [PDF]

Geo Data, 2020
The Hwangdo tidal flat has been subjected to local hydrodynamic changes caused by the construction of seawalls and bridges, which are changing the distribution of sediments and topographic characteristics.

Why haven't loose globular clusters collapsed yet? [PDF]

, 2007
We report on the discovery of a surprising observed correlation between the slope of the low-mass stellar global mass function (GMF) of globular clusters (GCs) and their central concentration parameter c=log(r_t/r_c), i.e.
