Black Hole Spectral States and Physical Connections
The dramatic changes seen in the X-ray spectral and timing properties of accreting black hole candidates (BHCs) provide important clues about the accretion and jet formation processes that occur in these systems. Dividing the different source behaviors into spectral states provides a framework for studying BHCs. To date, there have been three main classification schemes with Luminosity-based, C...
متن کاملIs there an upper limit to black hole masses ?
We make a case for the existence for ultra-massive black holes (UMBHs) in the Universe, but argue that there exists a likely upper limit to black hole masses of the order of M ∼ 1010M⊙. We show that there are three strong lines of argument that predicate the existence of UMBHs: (i) expected as a natural extension of the observed black hole mass bulge luminosity relation, when extrapolated to th...
متن کاملCharge quantization of axion-dilaton black holes.
We present axion-dilaton black-hole and multi-black-hole solutions of the low-energy string effective action. Under SL(2, R) electric-magnetic duality rotations only the "hair" (charges and asymptotic values of the fields) of our solutions is transformed. The functional form of the solutions is duality invariant. Axion-dilaton black holes with zero entropy and zero area of the horizon form a fa...
متن کاملLoris - A Redundant Array of Independent Physical Layers
The common storage stack as found in most operating systems has remained unchanged for several decades. In this stack, the RAID layer operates under the file system layer, at the block abstraction level. We argue that this arrangement of layers has fatal flaws. In this paper, we highlight its main problems, and present a new storage stack arrangement that solves these problems. An evaluation of...
متن کاملIs there an association between physical punishment in childhood and physical health in adulthood?
Since the landmark study on adverse childhood experiences (ACEs), there has been a growing interest in the relationship between ACEs and physical health. ACEs are associated with smoking, chronic obstructive pulmonary disorder, obesity, diabetes, cardiovascular disease, alcohol use, and liver disease in adults in a dose-dependent fashion. In the original study by Felitti et al, ACEs were more c...
