    • The Type Ic SN 1990B in NGC 4568 
      Clocchiatti, Alejandro; Suntzeff, Nicholas B.; Phillips, Mark M.; Filippenko, Alexei V.; Turatto, Massimo; Benetti, Stefano; Cappellaro, Enrico; Avilés, Roberto; Covarrubias, Ricardo; DeGiogia Eastwood, K.; Dickinson, Mark.; Gouiffes, Christian; Guhathakurta, Puragra; Hamuy Wackenhut, Mario; Heathcote, Steve R.; Leibundgut, Bruno; Matheson, Thomas; Navarrete, Mauricio; Pérez, M.; Phillips, Andrew; Piemonte, Antonello; Ruiz González, María Teresa; Shields, Joseph C.; Smith, Chris; Spinrad, Hyron; Sturch, Conrad R.; Tyson, J. Anthony; Wells, Lisa (2001-06-01)
      We present a study of the Type Ic supernova (SN) 1990B that includes most of the observations obtained from around the world. The combined data set comprises 84 BV (RI)c photometric points spanning approximately 360 days ...
    • Young, blue, and isolated stellar systems in the virgo cluster. I. 2D Optical spectroscopy 
      Bellazzini, Michele; Magrini, Laura; Jones, Michael G.; Sand, David J.; Beccari, Giacomo; Cresci, Giovanni; Spekkens, Kristine; Karunakaran, Ananthan; Adams, Elizabeth A. K.; Zaritsky, Dennis; Battaglia, Giuseppina; Seth, Anil; Cannon, John M.; Fuson, Jackson; Inoue, John L.; Mutlu Pakdil, Burçin; Guhathakurta, Puragra; Muñoz Vidal, Ricardo Rodrigo; Bennet, Paul; Crnojević, Denija; Caldwell, Nelson; Strader, Jay; Toloba, Elisa (IOP Publishing, 2022)
      We use panoramic optical spectroscopy obtained with the Very Large Telescope/MUSE to investigate the nature of five candidate extremely isolated low-mass star-forming regions (Blue Candidates; hereafter, BCs) toward ...
    • Young, blue, and isolated stellar systems in the virgo cluster. II. A new class of stellar system 
      Jones González, Michael Cristofer; Sand, David J.; Bellazzini, Michele; Spekkens, Kristine; Karunakaran, Ananthan; Adams, Elizabeth A. K.; Battaglia, Giuseppina; Beccari, Giacomo; Bennet, Paul; Cannon, John M.; Cresci, Giovanni; Crnojević, Denija; Caldwell, Nelson; Fuson, Jackson; Guhathakurta, Puragra; Haynes, Martha P.; Inoue, John L.; Magrini, Laura; Muñoz Vidal, Ricardo Rodrigo; Burçin, Mutlu-Pakdil; Seth, Anil; Strader, Jay; Toloba, Elisa; Zaritsky, Dennis (IOP Publishing, 2022)
      We discuss five blue stellar systems in the direction of the Virgo cluster, analogous to the enigmatic object SECCO 1 (AGC 226067). These objects were identified based on their optical and UV morphology and followed up ...
