Spectral Analysis of the Stromlo-APM Survey II. Galaxy luminosity function and clustering by spectral type [PDF]
, 1999 We study the luminosity function and clustering properties of subsamples of local galaxies selected from the Stromlo-APM survey by the rest-frame equivalent widths of their Halpha and Oii emission lines. The b_J luminosity function of star-forming galaxies has a significantly steeper faint-end slope than that for quiescent galaxies: the majority of sub-

Torques and angular momentum: Counter-rotation in galaxies and ring galaxies [PDF]
arXiv, 2016 We present an alternate origin scenario to explain the observed phenomena of (1) counter-rotation between different galaxy components and (2) the formation of ring galaxies. We suggest that these are direct consequences of the galaxy being acted upon by a torque which causes a change in its primordial spin angular momentum first observed as changes in ...

Disturbed isolated galaxies: indicators of a dark galaxy population? [PDF]
, 2006 We report the results of our search for disturbed (interacting) objects among very isolated galaxies. The inspections of 1050 northern isolated galaxies from KIG and 500 nearby, very isolated galaxies situated in the Local Supercluster yielded five and four strongly disturbed galaxies, respectively.

Galaxy protocluster candidates around z ~ 2.4 radio galaxies [PDF]
, 2010 We study the environments of 6 radio galaxies at 2.2 < z < 2.6 using wide-field near-infrared images. We use colour cuts to identify galaxies in this redshift range, and find that three of the radio galaxies are surrounded by significant surface overdensities of such galaxies. The excess galaxies that comprise these overdensities are strongly clustered,

Suppression of Star Formation in Galaxy Pairs [PDF]
arXivWe investigate the suppression of star formation in galaxy pairs based on the isolated galaxy pair sample derived from the SDSS survey. By comparing the star formation rate between late-type galaxies in galaxy pairs and those in the isolated environment, we detect the signal of star formation suppression in galaxy pairs at $d_p < 100$kpc and $200$kpc$ <
