Abell 1367: a high fraction of late-type galaxies displaying HI morphological and kinematic perturbations
Scott, T. C.; Brinks, E.; Cortese, L.; Boselli, A.; Bravo-Alfaro, H. (2018-04-21)To investigate the effects the cluster environment has on late-type galaxies (LTGs), we studied HI perturbation signatures for all Abell 1367 LTGs with HI detections. We used new Very Large Array HI observations combined ... -
CO in late-type galaxies within the central region of Abell 1367
Scott, T.C.; Usero, A.; Brinks, E.; Boselli, A.; Cortese, L.; Bravo-Alfaro, H. (2013-02)We present 12CO (J = 1→ 0) and 12CO (J = 2 →1) spectra for 19 bright, late–type galaxies (spirals) in the central region of the galaxy cluster Abell 1367 (z = 0.02) from observations make with the IRAM 30–m telescope. All ... -
Environmental effects in galaxy clusters : Infalling groups in Abell 85 and 1367
Bravo-Alfaro, H.; Granados, P.; Navarro-Poupard, F.; Scott, T.C.; Brinks, E.; Cortese, L.; Mayya, Y.D.; Durret, F. (2010-12-01)We are carrying out a multifrequency survey of late type galaxies in nearby clusters with the aim to investigate the effects exerted by both the very local and the global cluster environments. We report new VLA-HI images ... -
Galaxy evolution in Abell 85. I: Cluster substructure and environmental effects on the blue galaxy population
Bravo-Alfaro, H.; Caretta, C.A.; Lobo, C.; Durret, F.; Scott, T.C. (2009) -
H I and CO Emission in Blue Compact Dwarfs: Haro 2 and Haro 4/26
Bravo-Alfaro, H.; Brinks, E.; Baker, A.J.; Walter, F.; Kunth, D. (Astronomical Society of the Pacific, 2002)We present VLA HI imaging of two actively star-forming dwarf galaxies, Haro 2 and Haro 4, and of the spiral galaxy NGC 3510 (Haro 26), some 22' SW of Haro 4 (8.5kpc). We also present a map of the CO(1-0) distribution of ... -
H I and CO in Blue Compact Dwarf Galaxies: Haro 2 and Haro 4
Bravo-Alfaro, H.; Brinks, E.; Baker, A.J.; Walter, F.; Kunth, D. (2004-01) -
H I Distribution in Blue Compact Dwarf Galaxies
Bravo-Alfaro, H.; Brinks, E.; Kunth, D.; Matias, F. (Astronomical Society of the Pacific, 2000)We present VLA HI observations and preliminary results for two dwarf galaxies, Haro 2 (Mrk 33) and Haro 4 (Mrk 36, which are currently experiencing a burst of star formation. We analyze the distribution and kinematics of ... -
H I, CO and Near Infrared Observations of the BCD Galaxy Haro 2
Bravo-Alfaro, H.; Coziol, R.; Brinks, E.; Baker, A.J.; Walter, F.; Kunth, D. (2005) -
The HI Distribution in Two Blue Compact Dwarf Galaxies
Bravo-Alfaro, H.; Brinks, E.; Matias, F.; Baker, A.J.; Kunth, D. (Astronomical Society of the Pacific, 2001)We present VLA HI imaging of two actively star forming dwarf galaxies, Haro 2 and Haro 4, and include a map of the CO distribution of Haro 2 obtained with OVRO. We discuss some preliminary results based on the distribution ... -
Highly perturbed molecular gas in infalling cluster galaxies : the case of CGCG97-079
Scott, T.C.; Usero, A.; Brinks, E.; Bravo-Alfaro, H.; Cortese, L.; Boselli, A.; Argudo-Fernandez, M. (2015-10-11)We report on CO (J = 2 → 1) mapping with the IRAM 30-m HEtrodyne Receiver Array (HERA) of CGCG 97-079, an irregular galaxy in the merging galaxy cluster Abell 1367 (z = 0.022). We find that ˜80 per cent of the detected CO ... -
Multifrequency study of the blue compact dwarf Haro 2 : NIR imaging and optical spectroscopy

Probing evolutionary mechanisms in galaxy clusters: H I in Abell 1367
Scott, T.C.; Bravo-Alfaro, H.; Brinks, E.; Cortese, L.; Boselli, A. (2009)We are carrying out a programme of CO and interferometric H I observations in the nearby galaxy cluster Abell 1367. The aim is to better understand the processes driving the evolution of the ISM in late-type galaxies in ... -
Probing evolutionary mechanisms in galaxy clusters: neutral atomic hydrogen in Abell 1367
Scott, T.C.; Bravo-Alfaro, H.; Brinks, E.; Caretta, C.A.; Cortese, L.; Boselli, A.; Hardcastle, M.J.; Croston, J.H.; Plauchu, I. (2010)We present Very Large Array H i imaging data for a field in the NW of the galaxy cluster Abell 1367 (z= 0.02) in an attempt to probe the effect environment has on the interstellar medium of late-type spiral galaxies. Several ... -
