Characterizing the Star Cluster Populations in Stephan’s Quintet Using HST and JWST Observations

P. Aromal, S. C. Gallagher, К. В. Федотов, N. Bastian et autres

Abstract Stephan’s Quintet (SQ) is a local compact galaxy group system that exhibits significant star formation activity. A history of tidal interactions between its four member galaxies and a recent collision between an intruder galaxy and the original group are associated with …

Erratum: the SAMI Galaxy Survey: can we trust aperture corrections to predict star formation?

M. L. P. Gunawardhana, Samuel Richards, A. W. Green, L. M. R. Fogarty et autres

The paper 'The SAMI Galaxy Survey: can we trust aperture corrections to predict star formation?' was published in MNRAS 455, 2826 (2016). A mischaracterization of the data presented in Figs 10 and 11 of the original paper affects our conclusion on the …

Star clusters in tidal debris

Michael Rodruck, J. C. Charlton, Sanchayeeta Borthakur, A. Chitre et autres

ABSTRACT We present results of a Hubble Space Telescope (HST) UBVI-band study of star clusters in tidal tails, using new WFC3 and ACS imaging to complement existing WFPC2 data. We survey 12 tidal tails across seven merging systems, deriving ages and masses …

The SAMI survey: evidence for dynamical coupling of ionized gas and young stellar populations

Caroline Foster, Sam P Vaughan, Amelia Fraser-McKelvie, Sarah Brough et autres

ABSTRACT We explore local and global dynamical differences between the kinematics of ionized gas and stars in a sample of galaxies from Data Release 3 of the SAMI Galaxy Survey. We find better agreement between local (i.e. comparing on a spaxel-to-spaxel basis) …

The SAMI Survey: Evidence for dynamical coupling of ionised gas and young stellar populations

Caroline Foster, Sam P Vaughan, Amelia Fraser-McKelvie, Sarah Brough et autres

We explore local and global dynamical differences between the kinematics of ionised gas and stars in a sample of galaxies from Data Release 3 of the SAMI Galaxy Survey. We find better agreement between local (i.e., comparing on a spaxel-to-spaxel basis) velocities …

The SAMI Galaxy Survey: the relationship between galaxy rotation and the motion of neighbours

Yifan Mai, Sam P Vaughan, S. M. Croom, Jesse van de Sande et autres

ABSTRACT Using data from the SAMI Galaxy Survey, we investigate the correlation between the projected stellar kinematic spin vector of 1397 SAMI galaxies and the line-of-sight motion of their neighbouring galaxies. We calculate the luminosity-weighted mean velocity difference between SAMI galaxies and …

The SAMI Pilot Survey: stellar kinematics of galaxies in Abell 85, 168 and 2399

J. J. Bryant, Joss Bland‐Hawthorn, N. Scott, I. S. Konstantopoulos et autres

We present the SAMI Pilot Survey, consisting of integral field spectroscopy of 106 galaxies across three galaxy clusters, Abell 85, Abell 168 and Abell 2399. The galaxies were selected by absolute magnitude to have

The SAMI Galaxy Survey: cubism and covariance, putting round pegs into square holes

M. Goodwin, Gerald Cecil, C. Foster, Danail Obreschkow et autres

We present a methodology for the regularization and combination of sparse sampled and irregularly gridded observations from fibre-optic multiobject integral field spectroscopy. The approach minimizes interpolation and retains image resolution on combining subpixel dithered data. We discuss the methodology in the context …

The SAMI Galaxy Survey: instrument specification and target selection

J. Liske, J. Mould, M. Goodwin, S. M. Sweet et autres

The SAMI Galaxy Survey will observe 3400 galaxies with the Sydney-AAO Multi- object Integral-field spectrograph (SAMI) on the Anglo-Australian Telescope (AAT) in a 3-year survey which began in 2013. We present the throughput of the SAMI system, the science basis and specifications …
