Researchers are using data gathered before a deadly 2017 landslide in Greenland to show that deep learning may help predict seismic events such as earthquakes and volcanic eruptions.The tsunami result...
2018年分子和离子团簇戈登研究会议(The 2018 Gordon Research Conference on Molecular and Ionic Clusters)
2018年 分子和离子团簇戈登研究 会议
2018/1/12
The Gordon Research Conference on Molecular and Ionic Clusters focuses on the study of molecular aggregates and the fundamental molecular physics underpinning their structure, dynamics, and optical pr...
Crater clusters on Mars:Shedding light on martian ejecta launch conditions
Cratering Mars Meteorites Impact processes
2015/12/25
We have identified two classes of crater clusters on Mars. One class is “small clusters” (crater diameter D ~ tens m, spread over few hundred m), fitting our earlier calculations for the breakup of we...
Planetesimal clusters in a Keplerian disk I. gravitational evolution

2015/12/25
It was recently demonstrated by numerical simulations that a turbulent flow in a rotating system is capable of efficiently concentrating passively advected particles – having a density larger thanthe ...
OPTIMAL AND FAST DETECTION OF SPATIAL CLUSTERS WITH SCAN STATISTICS
SPATIAL CLUSTERS SCAN STATISTICS
2015/8/20
We consider the detection of multivariate spatial clusters in the Bernoulli
model with N locations, where the design distribution has weakly dependent
marginals. The locations are scanned with a rec...
Organizational and Institutional Genesis: The Emergence of High-Tech Clusters in the Life Sciences
Organizational and Institutional Genesis High-Tech Clusters
2015/7/3
Most research on the emergence of high-tech clusters samples on successful cases,
and works backwards to trace a narrative, often highlighting the role of specific
individuals or groups. Our appro...
The origin and initial mass function of young stellar clusters near the Galactic center are still poorly understood. Two of the more prominent ones, the Arches and Quintuplet clusters, may have formed...
The interplay between star formation and the nuclear environment of our Galaxy: deep X-ray observations of the Galactic centre Arches and Quintuplet clusters
n star formation the nuclear environment
2014/12/24
The Galactic centre (GC) provides a unique laboratory for a detailed examination of the interplay between massive star formation and the nuclear environment of our Galaxy. Here, we present a 100-ks Ch...
Ongoing assembly of massive galaxies by major merging in large groups and clusters from the SDSS
general surveys
2014/12/23
We investigate the incidence of major mergers creating massive (Mstar > 1011 M⊙) galaxies in present-day (z≤ 0.12) groups and clusters. Using a volume-limited sample of 845 groups with dark matter hal...
The evolution of star clusters: the resolved-star approach
Cluster candidates resolved-star
2014/12/23
We present the first results of a new technique to detect, locate, and characterize young dissolving star clusters. Using Hubble Space Telescope/Advanced Camera for Surveys archival images of the near...
Structural properties of central galaxies in groups and clusters
fundamental parameters structure.
2014/12/22
Using a statistically representative sample of 911 central galaxies (CENs) from the Sloan Digital Sky Survey (SDSS) Data Release 4 group catalogue, we study how the structure (shape and size) of the f...
THE PROPERTIES OF X-RAY LUMINOUS YOUNG STELLAR OBJECTS IN THE NGC 1333 AND SERPENS EMBEDDED CLUSTERS
new Chandra X-ray data NGC 1333
2014/12/22
We present new Chandra X-ray data of the NGC 1333 embedded cluster and combine these data with existing Chandra data, Spitzer photometry, and ground-based spectroscopy of both the NGC 1333 and Serpens...
The LTHE LUMINOSITY, MASS, AND AGE DISTRIBUTIONS OF COMPACT STAR CLUSTERS IN M83 BASED ON HUBBLE SPACE TELESCOPE/WIDE FIELD CAMERA 3 OBSERVATIONS
filters binning
2014/12/20
The newly installed Wide Field Camera 3 (WFC3) on the Hubble Space Telescope has been used to obtain multi-band images of the nearby spiral galaxy M83. These new observations are the deepest and highe...
The spatial distribution of star formation in the solar neighbourhood: do all stars form in dense clusters?

2014/12/20
We present a global study of low-mass, young stellar object (YSO) surface densities (ヒ) in nearby (<500 >pc) star-forming regions based on a comprehensive collection of Spitzer Space Telescope surveys...
