Weakly supervised machine learning for model-agnostic searches of new phenomena in the -ray sky
Michael Krämer, Silvia Manconi, Kathrin Nippel
The -ray sky, as observed by the Fermi Large Area Telescope, contains a significant number of unassociated sources that may point to new astrophysical populations or more exoti…
A MeerKAT search for persistent radio sources towards twenty-five localised Fast Radio Bursts
Lebogang L. Mfulwane, James O. Chibueze, Thulo P. Letsele +17
The discovery of persistent radio sources (PRSs) associated with repeating fast radio bursts (FRBs) has shed light on the immediate environments and possible progenitors of these F…
Radio emission from beyond the light cylinder in millisecond pulsars
Michael Kramer, Simon Johnston
A striking aspect of the radio profiles of many millisecond pulsars (MSPs) is that they consist of components separated from each other by regions lacking in emission. We devise a…
Localisation and host galaxy identification of new Fast Radio Bursts with MeerKAT
Inés Pastor-Marazuela, Alexa C. Gordon, Ben Stappers +18
Accurately localising fast radio bursts (FRBs) is essential for understanding their birth environments and for their use as cosmological probes. Recent advances in radio interferom…
A strategy for optimal material identification in solar dark photon absorption
Theresa M. Backes, Riccardo Catena, Michael Krämer
Dark photons with masses in the 1-100 eV range can be produced in the Sun and subsequently absorbed in terrestrial detectors, offering a promising avenue for probing hidden-sector…
A fast radio burst from the first 3 billion years of the Universe
Manisha Caleb, Themiya Nanayakkara, Benjamin Stappers +25
Fast radio bursts (FRBs) are enigmatic millisecond-duration signals which encode otherwise unattainable information on the plasma which permeates our Universe, providing insights i…
