    • Galaxy evolution explorer ultraviolet color-magnitude relations and evidence of recent star formation in early-type galaxies 

      Yi, S.K.; Yoon, S.-J.; Lee, Y.-W.; Ree, C.H.; Sohn, Y.-J.; Rey, S.-C.; Rhee, J.; Byun, Y.-I.; Kim, S.-W.; Kaviraj, S.; Deharveng, J.-M.; Boselli, A.; Donas, J.; Malina, R.; Milliard, B.; Rich, R.M.; Salim, S.; Friedman, P.G.; Martin, D.C.; Morrissey, P.; Small, T.; Barlow, T.; Forster, K.; Wyder, T.K.; Lee, J.-W.; Bianchi, L.; Heckman, T.M.; Szalay, A.S.; Jee, M.J.; Jelinsky, P.; Siegmund, O.; Welsh, B.; Madore, B.F.; Neff, S.; Schiminovich, D. (2005-01-20)
      We have used the Galaxy Evolution Explorer UV photometric data to construct a first near-UV (NUV) color-magnitude relation (CMR) for the galaxies preclassified as early-type by Sloan Digital Sky Survey studies. The NUV CMR ...

    • The look-back time evolution of far-ultraviolet flux from the brightest cluster elliptical galaxies at z <0.2 

      Ree, C.H.; Lee, Y.-W.; Yi, S.K.; Yoon, S.-J.; Sohn, Y.-J.; Rhee, J.; Sheen, Y.-K.; Rich, R.M.; Deharveng, J.-M.; Boselli, A.; Donas, J.; Milliard, B.; Kaviraj, S.; Schawinski, K.; Rey, S.-C.; Seibert, M.; Wyder, T.K.; Barlow, T.A.; Forster, K.; Friedman, P.G.; Martin, D.C.; Morrissey, P.; Small, T.; Bianchi, L.; Heckman, T.M.; Szalay, A.S.; Madore, B.F.; Neff, S.G.; Schiminovich, D.; Welsh, B.Y. (2007-12-01)
      We present the GALEXUV photometry of the elliptical galaxies in Abell clusters at moderate redshifts (z <0.2) for the study of the look-back time evolution of the UV upturn phenomenon. The brightest elliptical galaxies (M ...

    • Suppression of star formation in early-type galaxies by feedback from supermassive black holes 

      Schawinski, K.; Khochfar, S.; Kaviraj, S.; Yi, S.K.; Lee, Y.-W.; Boselli, A.; Donas, J.; Milliard, B.; Barlow, T.; Conrow, T.; Forster, K.; Friedman, P.G.; Martin, D.C.; Morrissey, P.; Seibert, M.; Small, T.; Wyder, T.K.; Neff, S.; Schiminovich, D.; Bianchi, L.; Heckman, T.; Szalay, A.; Madore, B.; Rich, R.M. (2006-08-24)
      Detailed high-resolution observations of the innermost regions of nearby galaxies have revealed the presence of supermassive black holes. These black holes may interact with their host galaxies by means of 'feedback' in ...
