The clear detection of an isotropic flux of very high energy neutrinos by the IceCube

Base on the ultraviolet radiation characteristics of cosmic celestial models and different morphological materials, the

Asymptotic giant branch (AGB) stars lose their envelopes by means of heavy mass-loss rates. Besides

Synthetic stellar libraries are quite popular to constrain the stellar pop- ulations (age and metallicity

Using Hubble Space Telescope (HST) observations, we have identified and characterised almost 50,000 pre-main sequence

"...if we never search, the chance of success is zero". This was the conclusion in
