I started studying Astrophysical black holes during my Master thesis, and I have not stopped since. I have carried out my studies abroad for several years, first in The Netherlands (Amsterdam), then in the United Kingdom (Southampton) before coming back to Italy in 2011. During my career I touched several lines of research: especially accreting neutron stars and ultra-luminous X-ray sources, but including also FRBs, GWs and even Inter-Galactic Medium&#8230;but the Physics of accretion-ejection in stellar-mass black holes remains my main scientific interest.<br \/>\nI study black-holes, and especially their jets, at all wavelengths, from radio to infrared to X-rays, and using as many telescopes as possible. In particular, I pioneered the use of infrared fast photometry to securely identify and study the fast variable emission from jets in X-ray binaries.<\/p>\n<p><a href=\"https:\/\/ui.adsabs.harvard.edu\/search\/q=orcid%3A0000-0002-0752-3301&amp;sort=date%20desc%2C%20bibcode%20desc&amp;p_=0\">List of publications<\/a><\/p>\n<p><a href=\"https:\/\/www.oa-roma.inaf.it\/heag\/wp-content\/uploads\/sites\/18\/2023\/10\/Casella_CV.pdf\">CV (updated February 2023<\/a><\/p>\n"},"caption":{"rendered":"<p>Piergiorgio (Pg) Casella &#8211; Staff researcher <\/p>\n"},"alt_text":"PG","media_type":"image","mime_type":"image\/png","media_details":{"width":806,"height":1202,"file":"2021\/10\/pg_photo.png","sizes":{"medium":{"file":"pg_photo-201x300.png","width":201,"height":300,"mime_type":"image\/png","source_url":"https:\/\/www.oa-roma.inaf.it\/heag\/wp-content\/uploads\/sites\/18\/2021\/10\/pg_photo-201x300.png"},"large":{"file":"pg_photo-687x1024.png","width":687,"height":1024,"mime_type":"image\/png","source_url":"https:\/\/www.oa-roma.inaf.it\/heag\/wp-content\/uploads\/sites\/18\/2021\/10\/pg_photo-687x1024.png"},"thumbnail":{"file":"pg_photo-150x150.png","width":150,"height":150,"mime_type":"image\/png","source_url":"https:\/\/www.oa-roma.inaf.it\/heag\/wp-content\/uploads\/sites\/18\/2021\/10\/pg_photo-150x150.png"},"medium_large":{"file":"pg_photo-768x1145.png","width":768,"height":1145,"mime_type":"image\/png","source_url":"https:\/\/www.oa-roma.inaf.it\/heag\/wp-content\/uploads\/sites\/18\/2021\/10\/pg_photo-768x1145.png"},"inspiro-loop":{"file":"pg_photo-806x320.png","width":806,"height":320,"mime_type":"image\/png","source_url":"https:\/\/www.oa-roma.inaf.it\/heag\/wp-content\/uploads\/sites\/18\/2021\/10\/pg_photo-806x320.png"},"inspiro-loop@2x":{"file":"pg_photo-806x640.png","width":806,"height":640,"filesize":787037,"mime_type":"image\/png","source_url":"https:\/\/www.oa-roma.inaf.it\/heag\/wp-content\/uploads\/sites\/18\/2021\/10\/pg_photo-806x640.png"},"full":{"file":"pg_photo.png","width":806,"height":1202,"mime_type":"image\/png","source_url":"https:\/\/www.oa-roma.inaf.it\/heag\/wp-content\/uploads\/sites\/18\/2021\/10\/pg_photo.png"}},"image_meta":{"aperture":"0","credit":"","camera":"","caption":"","created_timestamp":"0","copyright":"","focal_length":"0","iso":"0","shutter_speed":"0","title":"","orientation":"0","keywords":[]}},"post":null,"source_url":"https:\/\/www.oa-roma.inaf.it\/heag\/wp-content\/uploads\/sites\/18\/2021\/10\/pg_photo.png","_links":{"self":[{"href":"https:\/\/www.oa-roma.inaf.it\/heag\/wp-json\/wp\/v2\/media\/6533","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.oa-roma.inaf.it\/heag\/wp-json\/wp\/v2\/media"}],"about":[{"href":"https:\/\/www.oa-roma.inaf.it\/heag\/wp-json\/wp\/v2\/types\/attachment"}],"author":[{"embeddable":true,"href":"https:\/\/www.oa-roma.inaf.it\/heag\/wp-json\/wp\/v2\/users\/276"}],"replies":[{"embeddable":true,"href":"https:\/\/www.oa-roma.inaf.it\/heag\/wp-json\/wp\/v2\/comments?post=6533"}]}}
