Evidence for a fundamental stellar upper mass limit from clustered star formation, and some implications therof
Theoretical considerations lead to the expectation that stars should not have masses larger than about m_{max*}=60-120M_&sun;, while the observational evidence...
Evidence for Black Hole Event Horizons?, or Luminosities of Black Hole and Neutron Star Transients
Recently, models for Advection Dominated Accretion Flow (ADAF) have been shown to explain many of the quiescent properties of the X-ray and optical emission...
Evidence for Circumstellar Material in Type Ia Supernovae via Na I D Absorption Features
Type Ia Supernovae (SNe Ia) have high and homogeneous luminosities, making them an essential tool for measuring distances on a cosmic scale, useful to gauge the...
Evidence for coherent star-forming processes in the discs of spirals
This paper presents examples of star-forming phenomena in the discs of spirals which show symptoms of phase-coherence over kpc scales. Cases are found where...
Evidence for high velocity gas in giant H II regions
Spectroscopy of selected areas of the two Giant H II Regions (GHR) NGC 5471 and NGC 604 shows convincing evidence for the existence of ionized gas at high...
Evidence for leading spiral arm formation in NGC 7479
Azimuthal profiles of the spiral NGC 7479 in the B and I passbands have been analyzed using a subset of the azimuthal parameters proposed by Beckman and Cepa...
