Search and characterization of pulsars in southern globular clusters: new methodologies and results from an S-band survey

NAG, ROUHINUniversità degli Studi di Cagliari2026

This thesis explores the search for radio pulsars in globular clusters and the development of computational methods to enhance their detection under challenging observational conditions. Pulsars are rapidly rotating neutron stars---remnants of supernova explosions---and represent some of the most …

Exploiting pulsar timing at low radio frequencies: applications to Pulsar Timing Arrays, Interstellar medium and HII regions

IRACI, FRANCESCO ANGELOUniversità degli Studi di Cagliari2026

Pulsar timing at low radio frequencies offers a powerful way to investigate chromatic propagation effects in the ionised interstellar medium and to refine the modelling of noise processes in Pulsar Timing Array (PTA) analyses. A central element of this thesis is the combination of observations from …

THE IMPACT OF TRIPLE STELLAR SYSTEMS ON PROTOSTELLAR DISC DYNAMICS

CEPPI, SIMONEUniversità degli Studi di Milano2024

Theoretical challenges in modelling multiple stellar systems are mirrored by observational limitations, with multiplicity often concealed within disc cavities and hidden by surrounding material. Nevertheless, advancements in observational instruments are steadily revealing multiple stellar systems …
