	abstract = {We present new results of CO(1-0) spectroscopic observations of four Sloan Digital Sky Survey (SDSS) type 2 quasars (QSO2) at z \~{} 0.3, observed with the 30-m IRAM radio telescope. The QSO2 have infrared luminosities in the ultra-luminous infrared galaxies (ULIRG) regime. We confirm the CO(1-0) detection in one of our four QSO2, SDSS J1543-00, with L{\textquoteright}$_{CO}$ and M$_{H<SUB>2}$</SUB> (1.2 {\plusmn} 0.2) {\times} 10$^{10}$ K km s$^{-1}$ pc$^{2}$ and (9.4 {\plusmn} 1.4) {\times} 10$^{9}$ M $_{\&sun;}$, respectively. The full width at half maximum (FWHM) of the CO(1-0) line is =575 {\plusmn} 102 km s$^{-1}$. No CO(1-0) emission is detected in SDSS J0903+02, SDSS J1337-01, SDSS J1520-01 above 3 sigma, yielding upper limits on M(H$_{2}$) \~{} 9.6, 4.3 and 5.1 {\times} 10$^{9}$ M$_{\&sun;}$, respectively. We expand previous studies of the molecular gas content of intermediate z QSO2 into the ULIRG regime. Taking into account nine QSO2 at z \~{} 0.3-1.0 from the literature, we discuss the location of the 13 ULIRG QSO2 at z {\l}t} 1 with available L{\textquoteright}$_{CO}$ measurements in the L{\textquoteright}$_{CO}$ vs. z and L{\textquoteright}$_{CO}$ vs. L$_{FIR}$ diagrams, in comparison with other QSO1 and ULIRG star forming samples. Based on observations carried out with the IRAM 30 m radiotelescope.},

	abstract = {We present and analyse integral-field observations of six type II QSOs with z = 0.3-0.4, selected from the Sloan Digital Sky Survey (SDSS). Two of our sample are found to be surrounded by a nebula of warm ionized gas, with the largest nebula extending across 8 arcsec (40 kpc). Some regions of the extended nebulae show kinematics that are consistent with gravitational motion, while other regions show relatively perturbed kinematics: velocity shifts and linewidths too large to be readily explained by gravitational motion. We propose that a \~{}20 {\times} 20 kpc outflow is present in one of the galaxies. Possible mechanisms for triggering the outflow are discussed. In this object, we also find evidence for ionization both by shocks and by the radiation field of the AGN.},

	abstract = {We present long-slit spectroscopy, continuum and [OIII] {${\l}ambda$}5007 imaging data obtained with the Very Large Telescope and the Gran Telescopio Canarias of the type 2 quasar SDSS J0123+00 at z = 0.399. The quasar lies in a complex, gas-rich environment. It appears to be physically connected by a tidal bridge to another galaxy at a projected distance of \~{}100kpc, which suggests this is an interacting system. Ionized gas is detected to a distance of at least \~{}133kpc from the nucleus. The nebula has a total extension of \~{}180kpc. This is one of the largest ionized nebulae ever detected associated with an active galaxy. Based on the environmental properties, we propose that the origin of the nebula is tidal debris from a galactic encounter, which could as well be the triggering mechanism of the nuclear activity. SDSS J0123+00 demonstrates that giant, luminous ionized nebulae can exist associated with type 2 quasars of low radio luminosities, contrary to expectations based on type 1 quasar studies. Based on observations carried out at the European Southern Observatory (Paranal, Chile) with FORS2 on VLT-UT1 [programme 69.A-0123(A)] and at the Observatory Roque de los Muchachos (La Palma, Spain) with OSIRIS on GTC (programme GTC27-09A).
