Properties of the extremely HI-massive galaxy HIZOA J0836-43
Renee C. Kraan-Korteweg, Michelle Cluver, Tom H. Jarrett +1
Little is known about the properties of extremely massive HI-galaxies. They are extremely scarce and are - according to hierarchical structure formation - only forming now (z < 1).…
Quantified Morphology of HI Disks in the Universe
B. W. Holwerda, W. J. G. de Blok, A. Bouchard +3
he upcoming new perspective of the high redshift Universe in the 21 cm line of atomic hydrogen opens possibilities to explore topics of spiral disk evolution, hitherto reserved for…
QED vacuum fluctuations and induced electric dipole moment of the neutron
C. A. Dominguez, H. Falomir, M. Ipinza +3
Quantum fluctuations in the QED vacuum generate non-linear effects, such as peculiar induced electromagnetic fields. In particular, we show here that an electrically neutral partic…
Scanning the Parameter Space of Holographic Superconductors
Obinna C. Umeh
We study various physical quantities associated with holographic s-wave superconductors as functions of the scaling dimensions of the dual condensates. A bulk scalar field with neg…
Measuring the cosmic ray acceleration efficiency of a supernova remnant
E. A. Helder, J. Vink, C. G. Bassa +7
Cosmic rays are the most energetic particles arriving at earth. Although most of them are thought to be accelerated by supernova remnants, the details of the acceleration process a…
Power-law cosmic expansion in f(R) gravity models
Naureen Goheer, Julien Larena, Peter K. S. Dunsby
We show that within the class of f(R) gravity theories, FLRW power-law perfect fluid solutions only exist for R^n gravity. This significantly restricts the set of exact cosmologica…
