Arianna Di Cintio, researcher at the Instituto de Astrofísica de Canarias and professor at the University of La Laguna, was awarded yesterday Monday, March 11, at the awards gala held for the Institutional Day of the University of La Laguna. The award corresponds to the junior category, referring to research personnel born after 1984, recognizing the quality of research at the scientific and social level and for its particular value and interest in the socioeconomic environment, its social repercussion and international impact. Di Cintio is an Italian researcher specialized in galaxy

Accretion disks around compact objects are expected to enter an unstable phase at high luminosity. One instability may occur when the radiation pressure generated by accretion modifies the disk viscosity, resulting in the cyclic depletion and refilling of the inner disk on short timescales. Such a scenario, however, has only been quantitatively verified for a single stellar-mass black hole. Although there are hints of these cycles in a few isolated cases, their apparent absence in the variable emission of most bright accreting neutron stars and black holes has been a continuing puzzle.
