"The Most Powerful
Persistent Jets through Cosmic Time"
About 10% of accreting
supermassive black holes at the center of galaxies are capable
of launching extreme relativistic jets. These AGNs and their
jets have been studied for decades, from radio up to gamma-rays.
However, many open questions still remain about the processes
powering these powerful monsters. When, in the history of time,
were the most luminous jets more numerous, and what is their
connection with fast supermassive black-holes growth in the
early universe? Are the radiating particles leptons or hadrons?
Is the so-called 'blazar sequence' real or just a selection
effect? In this talk, I will highlight how we can tackle some of
these open issues through means of multiwavelegth studies, in
particular exploiting the capabilities of current high-energy
experiments.
About the Speaker:
Lea Marcotulli is currently an Einstein Fellow at Yale
University since Sept. 2021. She graduated with her PhD in
Physics from Clemson University in May 2021. She is a
high-energy astrophysicist, and her main research focus is
studying blazars at high-redshift and their connection to
supermassive black hole growth, both through single sources
studies and population studies at X- and gamma-rays. She is also
the proud co-founder of the science outreach YouTube channel
(On) Planet Nine.
