Serendipitous discovery of a spiral host in a 2 Mpc double-double lobed radio galaxy
Sagar Sethi, Agnieszka Kuźmicz, Dominika Hunik +1
We present the serendipitous discovery of a double-double radio galaxy (DDRG) with a projected linear size exceeding 2 Mpc, hosted by a spiral galaxy. This unique combination of a…
Conformal flow on and weak field integrability in AdS
Piotr Bizoń, Ben Craps, Oleg Evnin +3
We consider the conformally invariant cubic wave equation on the Einstein cylinder for small rotationally symmetric initial data. This simple equat…
Design of the SABAT system for underwater detection of dangerous substances
M. Silarski, D. Hunik, M. Smolis +2
We present status of simulations used to design a novel device for the detection of hazardous substances in the aquatic environment using neutron activation. Unlike the other consi…
Discovery of ultra-steep spectrum giant radio galaxy with recurrent radio jet activity in Abell 449
D. Hunik, M. Jamrozy
We report a discovery of a 1.3 Mpc diffuse radio source with extremely steep spectrum fading radio structures in the vicinity of the Abell 449 cluster of galaxies. Its extended dif…
