Deep transfer learning for star cluster classification: I. application to the PHANGS–HST survey [PDF]
Monthly notices of the Royal Astronomical Society, 2019 We present the results of a proof-of-concept experiment that demonstrates that deep learning can successfully be used for production-scale classification of compact star clusters detected in Hubble Space Telescope(HST) ultraviolet-optical imaging of ...

Star cluster catalogues for the LEGUS dwarf galaxies [PDF]
Monthly notices of the Royal Astronomical Society, 2019 We present the star cluster catalogues for 17 dwarf and irregular galaxies in the HST Treasury Program ‘Legacy ExtraGalactic UV Survey’ (LEGUS). Cluster identification and photometry in this sub-sample are similar to that of the entire LEGUS sample, but ...

Young star cluster populations in the E-MOSAICS simulations [PDF]
Monthly notices of the Royal Astronomical Society, 2019 We present an analysis of young star clusters (YSCs) that form in the E-MOSAICS cosmological, hydrodynamical simulations of galaxies and their star cluster populations.

The Double Star Plasma Electron and Current Experiment [PDF]
Annales Geophysicae, 2005 The Double Star Project is a collaboration between Chinese and European space agencies, in which two Chinese magnetospheric research spacecraft, carrying Chinese and European instruments, have been launched into equatorial (on 29 December 2003) and ...

Planetary systems in a star cluster I: the Solar system scenario [PDF]
Monthly notices of the Royal Astronomical Society, 2019 Young stars are mostly found in dense stellar environments, and even our own Solar system may have formed in a star cluster. Here, we numerically explore the evolution of planetary systems similar to our own Solar system in star clusters.

Early-forming Massive Stars Suppress Star Formation and Hierarchical Cluster Assembly
The Astrophysical Journal, 2023 Feedback from massive stars plays an important role in the formation of star clusters. Whether a very massive star is born early or late in the cluster formation timeline has profound implications for the star cluster formation and assembly processes. We

Super-solar Metallicity Stars in the Galactic Center Nuclear Star Cluster: Unusual Sc, V, and Y Abundances [PDF]
Astrophysical Journal, 2018 We present adaptive-optics assisted near-infrared high-spectral-resolution observations of late-type giants in the nuclear star cluster of the Milky Way.

Performance Evaluation of Beacon-Enabled Mode for IEEE 802.15.4 Wireless Sensor Network
Emitter: International Journal of Engineering Technology, 2013 IEEE 802.15.5 standard support structure of star and peer-to-peer network formation. Strating from these, the cluster tree network can be built as a special case of peer-to-peer network to increse coverage area.

Massive star cluster formation under the microscope atz = 6 [PDF]
Monthly notices of the Royal Astronomical Society, 2018 We report on a superdense star-forming region with an effective radius (R-e) smaller than 13 pc identified at z = 6.143 and showing a star formation rate density Sigma(SFR) similar to 1000 M-circle dot yr(-1) kpc(-2) (or conservatively > 300 M-circle dot
