A new investigation of the binary HD 48099

L. Mahy, G. Rauw, F. Martins +5

With an orbital period of about 3.078 days, the double-lined spectroscopic binary HD 48099 is, still now, the only short-period O+O system known in the Mon OB2 association. Even th…

What is a Cool-Core Cluster? A Detailed Analysis of the Cores of the X-ray Flux-Limited HIFLUGCS Cluster Sample

Daniel S. Hudson, Rupal Mittal, Thomas H. Reiprich +3

We use the largest complete sample of 64 galaxy clusters (HIghest X-ray FLUx Galaxy Cluster Sample) with available high-quality X-ray data from Chandra, and apply 16 cool-core diag…

Towards a Supersymmetric Generalization of the Schwarzschild Black Hole

J. C. López-Domínguez, O. Obregón, S. Zacarías

The Wheeler-DeWitt (WDW) equation for the Kantowski-Sachs model can also be understood as the WDW-equation corresponding to the Schwarzschild black hole due to the well known diffe…

Scalar field in the Bianchi I: Non commutative classical and Quantum Cosmology

J. Socorro, Luis O. Pimentel, C. Ortiz +1

Using the ADM formalism in the minisuperspace, we obtain the commutative and noncommutative exact classical solutions and exact wave function to the Wheeler-DeWitt equation with an…

A note on Verhulst's logistic equation and related logistic maps

M. Ranferi Gutierrez, M. A. Reyes, H. C. Rosu

We consider the Verhulst logistic equation and a couple of forms of the corresponding logistic maps. For the case of the logistic equation we show that using the general Riccati so…

Radio Properties of Brightest Cluster Members

H. Andernach, M. E. Ramos-Ceja

We searched the literature for radio images and fluxes of brightest cluster members (BCMs) in 1169 Abell clusters, selected on the basis of their BM or RS type or on textual notes…
