      Introduction: Ultraluminous X-ray sources (ULXs) represent an extreme class of accreting compact objects: from the identification of some of the accretors as neutron stars to the detection of powerful winds travelling at ...

    • On the encounter between the GASP galaxy JO36 and the radio plume of GIN 049 

      Ignesti, Alessandro; Brienza, Marisa; Vulcani, Benedetta; Poggianti, Bianca M.; Marasco, Antonino; Smith, Rory; Hardcastle, Martin; Botteon, Andrea; Roberts, Ian D.; Fritz, Jacopo; Paladino, Rosita; Gitti, Myriam; Wolter, Anna; Tomčić, Neven; McGee, Sean; Moretti, Alessia; Gullieuszik, Marco; Drabent, Alexander (2023-10-16)
      We report the serendipitous discovery of an unprecedented interaction between the radio lobe of a radio galaxy and a spiral galaxy. The discovery was made thanks to LOFAR observations at 144 MHz of the galaxy cluster A160 ...

    • The Orbit of NGC 5907 ULX-1 

      Belfiore, Andrea; Salvaterra, Ruben; Sidoli, Lara; Israel, Gian Luca; Stella, Luigi; De Luca, Andrea; Mereghetti, Sandro; Esposito, Paolo; Pintore, Fabio; D’Aì, Antonino; Rodrìguez Castillo, Guillermo; Walton, Dominic J.; Fürst, Felix; Magistrali, Danilo; Wolter, Anna; Imbrogno, Matteo (2024-04-09)
      We report on the orbit of the binary system powering the most extreme ultraluminous X-ray pulsar known to date: NGC 5907 ULX-1 (hereafter ULX1). ULX1 has been the target of a substantial multi-instrument campaign, mainly ...
