Intermittent activity of radio sources. Accretion instabilities and jet precession
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2011/1/4
We consider the radiation pressure instability operating on short timescales 10^3 - 10^6 years in the accretion disk around a supermassive black hole as the origin of the intermittent activity of radi...
Dependence of Star Formation Activity On Stellar Mass and Environment From the Redshift One LDSS-3 Emission Line Survey (ROLES)
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2010/12/27
Using the sample from the \it Redshift One LDSS3 Emission line Survey \rm (ROLES), we probe the dependence of star formation rate (SFR) and specific star formation rate (sSFR) as a function of stellar...
