A -ray determination of the Universe's star-formation history

LAT Collaboration, M. Ajello, K. Helgason +4

The light emitted by all galaxies over the history of the Universe produces the extragalactic background light (EBL) at ultraviolet, optical, and infrared wavelengths. The EBL is a…

Dust emission profiles of DustPedia galaxies

A. V. Mosenkov, M. Baes, S. Bianchi +19

Most radiative transfer models assume that dust in spiral galaxies is distributed exponentially. In this paper our goal is to verify this assumption by analysing the two-dimensiona…

Ultra-steep spectrum emission in the merging galaxy cluster Abell 1914

S. Mandal, H. T. Intema, T. W. Shimwell +14

A number of radio observations have revealed the presence of large synchrotron-emitting sources associated with the intra-cluster medium. There is strong observational evidence tha…
