  • The Evershed Effect with 0.2 arcsec Angular Resolution
    We present a preliminary analysis of penumbral spectra observed with unprecedented angular resolution (0.2 arcsec) using the new Swedish 1-m Solar Telescope. The use of a non-magnetic line allows us to measure Doppler shifts without magnetic contamination. The observed Doppler shifts depend on the part of the line used for measuring, indicating

  • The evolution of the disc variability along the hard state of the black hole transient GX 339-4
    We report on the analysis of hard-state power spectral density function (PSD) of GX 339-4 down to the soft X-ray band, where the disc significantly contributes to the total emission. At any luminosity probed, the disc in the hard state is intrinsically more variable than in the soft state. However, the fast decrease of disc variability as a

  • The evolution of the Light Elements, Be and B (also Li), in the Galaxy
    We consider the evolution of the light elements, especially beryllium and boron but also lithium, in the Galaxy as derived from observations within 1 kpc of the Sun. The interest in Li has much to do with the evaluation of the universal baryon abundance via primordial nucleosynthesis, but the difficulties of interpretation have led to the need to

  • The Extended Bar and Grand-Design Spirals in NGC 5248
    We present a study of the grand-design spiral galaxy NGC 5248 (Jogee et al. 2002a,b) based on a combination of multi-wavelength % optical, near-infrared, and CO (J=1--O) observations and hydrodynamical modeling.

  • The Extensive Age Gradient of the Carina Dwarf Galaxy
    The evolution of small systems such as dwarf spheroidal galaxies (dSphs) is likely to have been a balance between external environmental effects and internal processes within their own relatively shallow potential wells. Assessing how strong such environmental interactions may have been is therefore an important element in understanding the

  • The Faint "Heartbeats" of IGR J17091-3624: An Exceptional Black Hole Candidate
    We report on the first 180 days of Rossi X-Ray Timing Explorer observations of the outburst of the black hole candidate IGR J17091-3624. This source exhibits a broad variety of complex light curve patterns including periods of strong flares alternating with quiet intervals. Similar patterns in the X-ray light curves have been seen in the (up to now
