  • Synthetic photometry of M-type AGB stars with JWST & WISE
  • 2017
  • Rapport (övrigt vetenskapligt/konstnärligt)abstract
    • In this study we present a data set of synthetic photometry of M-type AGB stars for JWST, WISE and a filter set that will be referred to as the generic lter set, consisting of: UX BX B V R I J J2m H H2m Ks2m K L L' M M'. 106 dierent models compromised of 4741 spectra have been processed for the three filter sets. We have also fitted the models to eight observations of M-type AGB stars made by WISE, showing that the models fairly well can recreate observations but that there is definitely still room for improvements. The resulting photometric files can be accessed at http://www.astro.uu.se/AGBmodels/ABmags

  • Stellar kinematics in blue compact galaxies
  • 2009
  • Rapport (övrigt vetenskapligt/konstnärligt)abstract
    • In a programme of observations of local luminous blue compact galaxies (BCGs), we are investigating kinematics by using tracers of both stars and ionized gas. Here we summarise our program and present new data on the local Lyman break galaxy analogue Haro 11. From spatially-resolved spectroscopy around the near-infrared Ca II triplet, we find that its stars and ionized gas have similar velocity fields. Our programme so far indicates however that emission line velocities can differ locally by a few tens of km/s from the Ca II values. Comparing our data to simple stellar population models, we assess which stellar population the Ca II triplet traces and its potential beyond the local universe.

  • MERLIN radio observations of two recent supernovae in Arp299 : SN2010O & SN2010P
  • 2010
  • Rapport (övrigt vetenskapligt/konstnärligt)abstract
    • We report MERLIN radio observations of the two recent supernovae in Arp299; SN2010P and SN2010O (CBET #2145 and CBET #2144, respectively). Observations of Arp299 were made between 1900UT 29th Jan 2010 and 0150UT 1st Feb 2010 at 4994MHz. The previously known compact radio structure of Arp299, including the nuclear starburst components associated with A=IC694 and B1=the southernmost nucleus of NGC3690 are detected (Neff, Ulvestad & Teng 2004, ApJ, 611, 186; Ulvestad 2009 AJ, 138, 152; Perez-Torres et al 2009, A&A 507, 17).
