  • A possible relation between global CO excitation and massive molecular outflows in local ULIRGs 
    Montoya Arroyave, Isabel; Cicone, Claudia; Andreani, P.; Weiss, A.; De Breuck, C; Lundgren, A.; Severgnini, P.; Hagedorn, B.; Hagedorn, Jan Bendix; Rubinur, K.; Khatun, Rubinur; Baumschlager, Bernhard; Makroleivaditi, E. (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2024)
    Local ultra-luminous infrared galaxies (ULIRGs) have been observed to host ubiquitous molecular outflows, including the most massive and powerful ever detected. These sources have also exceptionally excited global, ...
  • A sensitive APEX and ALMA CO(1-0), CO(2-1), CO(3-2), and [CI](1-0) spectral survey of 40 local (ultra-)luminous infrared galaxies 
    Montoya Arroyave, Isabel; Cicone, Claudia; Makroleivaditi, E.; Weiss, A.; Lundgren, A.; Severgnini, P.; De Breuck, Carlos; Baumschlager, Bernhard; Schimek, Alice; Shen, Sijing; Aravena, M. (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)
    We present a high sensitivity, ground-based spectral line survey of low- J carbon monoxide (CO( J up  →  J up  − 1) with J up  = 1, 2, 3) and neutral carbon [CI] 3 P 1 − 3 P 0 ([CI](1–0)) in 36 local ultra-luminous infrared ...
  • Another X-ray UFO without a momentum-boosted molecular outflow: ALMA CO(1–0) observations of the galaxy pair IRAS 05054+1718 
    Bonanomi, Francesca; Cicone, Claudia; Severgnini, Paola; Braito, Valentina; Vignali, Cristian; Reeves, James N.; Sirressi, Mattia; Montoya Arroyave, Isabel; Ceca, Roberto Della; Ballo, Lucia; Dotti, Massimo (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)
    We present Atacama Large Millimetre/submillimetre Array (ALMA) CO(1–0) observations of the nearby infrared luminous (LIRG) galaxy pair IRAS 05054+1718 (also known as CGCG 468-002), as well as a new analysis of X-ray data ...
  • The optically elusive, changing-look active nucleus in NGC 4156 
    Tozzi, Giulia; Lusso, Elisabeta; Casetti, Lapo; Romoli, Marco; Andreuzzi, Gloria; Montoya Arroyave, Isabel; Nardini, Emanuele; Cresci, Giovanni; Middei, Riccardo; Bertolini, Silvia; Calabretto, Paolo; Cammelli, Vieri; Cuadra, Francisco; Dalla Ragione, Marco; Marconcini, Cosimo; Miceli, Adriano; Mini, Irene; Palazzini, Martina; Rotellini, Giorgio; Saccardi, Andrea; Samà, Lavinia; Sangalli, Mattia; Serafini, Lorenzo; Spaccino, Fabio (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)
    We report on the changing-look nature of the active galactic nucleus (AGN) in the galaxy NGC 4156, which was serendipitously discovered thanks to data acquired in 2019 at the Telescopio Nazionale Galileo (TNG) during a ...
