The cosmic radio dipole: Bayesian estimators on new and old radio surveys
J. D. Wagenveld, H-R. Klöckner, D. J. Schwarz
The cosmic radio dipole is an anisotropy in the number counts of radio sources, analogous to the dipole seen in the cosmic microwave background (CMB). Measurements of source counts…
Weakly interacting massive particle cross section limits from LOFAR observations of dwarf spheroidal galaxies
L. Gajović, F. Welzmüller, V. Heesen +8
Weakly interacting massive particles (WIMPs) can self-annihilate, thus providing us with a way to indirectly detect dark matter (DM). Dwarf spheroidal (dSph) galaxies are excellent…
Inference of the cosmic rest-frame from supernovae Ia
Nick Horstmann, Yannic Pietschke, Dominik J. Schwarz
We determine the proper motion of the Solar system from the Pantheon sample of supernovae (SNe) of type Ia. The posterior distribution of the Solar system proper velocity, its dire…
Galaxy power spectrum and biasing results from the LOFAR Two-metre Sky Survey (first data release)
Prabhakar Tiwari, Ruiyang Zhao, Jinglan Zheng +3
The LOFAR Two-metre Sky Survey (LoTSS) is an ongoing survey aiming to observe the entire Northern sky, providing an excellent opportunity to study the distribution and evolution of…
Extreme-Value Distributions and Primordial Black-Hole Formation
Florian Kuhnel, Dominik J. Schwarz
We argue that primordial black-hole formation must be described by means of extreme-value theory. This is a consequence of the large values of the energy density required to initia…
The contribution of discrete sources to the sky temperature at 144 MHz
M. J. Hardcastle, T. W. Shimwell, C. Tasse +7
In recent years, the level of the extragalactic radio background has become a point of considerable interest, with some lines of argument pointing to an entirely new cosmological s…
