Using Narrow Band Photometry to Classify Stars and Brown Dwarfs
A. K. Mainzer, Ian S. McLean, J. L. Sievers +1
We present a new system of narrow band filters in the near infrared that can be used to classify stars and brown dwarfs. This set of four filters, spanning the H band, can be used…
X-ray Reflection from Inhomogeneous Accretion Disks: I. Toy Models and Photon Bubbles
D. R. Ballantyne, N. J. Turner, O. M. Blaes
Numerical simulations of the interiors of radiation dominated accretion disks show that significant density inhomogeneities can be generated in the gas. Here, we present the first…
The black hole mass versus velocity dispersion relation in QSOs/Active Galactic Nuclei: observational appearance and black hole growth
Qingjuan Yu, Youjun Lu
Studies of massive black holes (BHs) in nearby galactic centers have revealed a tight correlation between BH mass and galactic velocity dispersion. In this paper we investigate how…
Constraints on QSO models from a relation between the QSO luminosity function and the local black hole mass function
Qingjuan Yu, Youjun Lu
QSOs are believed to be powered by accretion onto massive black holes (BHs). In this paper, assuming that each central BH in nearby galaxies has experienced the QSO phase and ignor…
Mapping the dark matter using weak lensing
Henk Hoekstra
Weak gravitational lensing of distant galaxies by foreground structures has proven to be a powerful tool to study the mass distribution in the universe. The advent of panoramic cam…
The consequences of nuclear electron capture in core collapse supernovae
W. R. Hix, O. E. B. Messer, A. Mezzacappa +5
The most important weak nuclear interaction to the dynamics of stellar core collapse is electron capture, primarily on nuclei with masses larger than 60. In prior simulations of co…
