On negative eigenvalues of two-dimensional Schroedinger operators with singular potentials

Martin Karuhanga, Eugene Shargorodsky

We present upper estimates for the number of negative eigenvalues of two-dimensional Schroedinger operators with potentials generated by Ahlfors regular measures of arbitrary dimen…

Extreme & High Synchrotron Peak Blazars beyond 4FGL: The 2BIGB -ray catalogue

Bruno Arsioli, Yu-Ling Chang, Blessing Musiimenta

This paper presents the results of a -ray likelihood analysis over all the extreme and high synchrotron peak blazars (EHSP & HSP) from the 3HSP catalogue. We investigate 201…

New mysteries and challenges from the Toothbrush relic: wideband observations from 550 MHz to 8 GHz

K. Rajpurohit, M. Hoeft, F. Vazza +10

Radio relics are diffuse extended synchrotron sources that originate from shock fronts induced by galaxy cluster mergers. The actual particle acceleration mechanism at the shock fr…

Are the observed gaps in protoplanetary discs caused by growing planets?

Nelson Ndugu, Bertram Bitsch, Edward Jurua

Recent detailed observations of protoplanetary discs revealed a lot of sub-structures which are mostly ring-like. One interpretation is that these rings are caused by growing plane…

The Structure of a Quasi-Keplerian Accretion Disk around Magnetized Stars

Isaac Habumugisha, Edward Jurua, Solomon B. Tessema +1

In this paper, we present the complete structure of a quasi-Keplerian thin accretion disk with an internal dynamo around a magnetized neutron star. We assume a full quasi-Keplerian…

On the discrete spectrum of Schroedinger operators with Ahlfors regular potentials in a strip

Martin Karuhanga

In this paper, quantitative upper estimates for the number of eigenvalues lying below the essential spectrum of Schroedinger operators with potentials generated by Ahlfors regular…
