XMM-Newton measures the power of black-hole driven outflows in galaxies

My research was the topic of a press release by the European Space Agency on 27 February 2012. Here is an highlight:

Astronomers using ESA’s XMM-Newton X-ray Observatory have discovered that ultra-fast outflows are quite common in active galaxies. About 40 per cent of the sources in their sample show outflows that arise from the vicinity of the central black holes. By estimating the mass and energy released by the outflows, the astronomers have identified them as major agents in the feedback processes required by models of galactic evolution to explain the observed correlation between the mass of black holes and the stellar content of their host galaxies…

Ultra-fast Outflows help monster black holes shape their galaxies

My research was the topic of a NASA press release on 27 February 2012. Here is an highlight:

A curious correlation between the mass of a galaxy’s central black hole and the velocity of stars in a vast, roughly spherical structure known as its bulge has puzzled astronomers for years. An international team led by Francesco Tombesi at NASA’s Goddard Space Flight Center in Greenbelt, Md., now has identified a new type of black-hole-driven outflow that appears to be both powerful enough and common enough to explain this link…

Là dove osano i buchi neri

My research was the topic of a press release by the National Italian Institute for Astrophysics (INAF) on 5 February 2013. Here is an highlight (N.B. it is written in Italian):

Ecco l’identikit dei cosiddetti “warm absorbers”, gli strati di plasma ionizzato più remoti fra quelli emessi, nelle galassie a nucleo attivo, dal buco nero centrale. A tracciarlo, un giovane astrofisico marchigiano di stanza alla NASA, Francesco Tombesi…

Ufo, “getti volanti” identificati

My research was the topic of a press release by the National Italian Institute for Astrophysics (INAF) on 26 July 2010. Here is an highlight (N.B. it is written in Italian):

Ebbene, gli Ufo esistono. La dimostrazione in due articoli di Francesco Tombesi, un giovane astrofisico italiano che lavora alla Nasa. Ma non sono navicelle aliene, bensì Ultra Fast Outflows (UFO, appunto), getti di materia espulsi da buchi neri supermassicci a velocità paragonabili a quella della luce…

Dai buchi neri sgorgano gli UFO

My research was the topic of a press release by the National Italian Institute for Astrophysics (INAF) on 27 February 2012. Here is an highlight (N.B. it is written in Italian):

Si chiamano Ultra-Fast Outflows (UFO), e vengono espulsi dal cuore di molte galassie con nucleo attivo. Un team di astronomi, guidato dagli italiani Francesco Tombesi della NASA e Massimo Cappi dell’INAF, ne ha misurato le proprietà con il satellite XMM dell’ESA…
