    • Formation of S0s in extreme environments : I: clues from kinematics and stellar populations 

      Coccato, Lodovico; Jaffé, Yara L.; Cortesi, Arianna; Merrifield, Michael; Johnston, Evelyn J.; Del Pino, Bruno Rodŕiguez; Haeussler, Boris; Chies-Santos, Ana Leonor; Oliveira, Claudia Lucia Mendes de; Sheen, Yun-Kyeong; Menéndez-Delmestre, Karín (2020) [Artigo de periódico]
      Despite numerous efforts, it is still unclear whether lenticular galaxies (S0s) evolve from spirals whose star formation was suppressed, or formed trough mergers or disc instabilities. In this paper we present a pilot study ...

    • Profile comparison of the 6–9 μm polycyclic aromatic hydrocarbon bands in starburst-dominated galaxies 

      Canelo, Carla Martinez; Sales, Dinalva Aires de; Friaça, Amâncio César Santos; Pastoriza, Miriani Griselda; Menéndez-Delmestre, Karín (2021) [Artigo de periódico]
      Polycyclic aromatic hydrocarbons (PAHs) are of great astrochemical and astrobiological interest due to their potential to form prebiotic molecules. We analyse the 7.7 and 8.6 μm PAH bands in 126 pre-dominantly starburst-dominated ...

    • The complex globular cluster system of the S0 galaxy NGC 4382 in the outskirts of the Virgo Cluster 

      Escudero, Carlos G.; Cortesi, Arianna; Faifer, Favio Raúl; Sesto, Leandro A.; Castelli, Analía Smith; Johnston, Evelyn J.; Reynaldi, Victoria; Chies-Santos, Ana Leonor; Salinas, Ricardo; Menéndez-Delmestre, Karín; Gonçalves, Thiago Signorini; Grossi, Marco; Oliveira, Claudia Lucia Mendes de (2022) [Artigo de periódico]
      NGC 4382 is a merger-remnant galaxy that has been classified as morphological type E2, S0, and even Sa. In this work, we performed a photometric and spectroscopic analysis of the globular cluster (GC) system of this peculiar ...
