    Large-scale radio nebula around the Ultra-Luminous X-ray Source IC 342 X-1
    We present discovery of a radio nebula associated with the ultraluminous X-ray source (ULX) IC 342 X-1 using the Very Large Array (VLA). Taking the surrounding...

    Long-term photometry of WX Arietis: evidence for eclipses and dips
    We present R-band photometry of the SW Sex-type cataclysmic variable WX Arietis made in October 1995 and August 1998-February 1999. Contrary to previous results...

    Long-term variability in the quiescent X-ray transient V404 Cyg
    We present the results of optical and infrared photometry of the quiescent X-ray transient V404 Cyg during the period 1992-2003.

    Low-level accretion in neutron star X-ray binaries
    We search the literature for reports on the spectral properties of neutron star low-mass X-ray binaries when they have accretion luminosities between 1034 and...

    MAGIC search for VHE γ-ray emission from AE Aquarii in a multiwavelength context
    Context. It has been claimed that the nova-like cataclysmic variable AE Aquarii (AE Aqr) is a very-high-energy (VHE, E> 100 GeV) source both on observational...

    Magnetospheric accretion onto the T Tauri star AA Tauri. I. Constraints from multisite spectrophotometric monitoring
    We have monitored the photometric, spectroscopic and polarimetric variations of the classical T Tauri star (CTTS) AA Tau over a period of a month. The light...

    Mass accretion rates from multiband photometry in the Carina Nebula: the case of Trumpler 14
    Context. We present a study of the mass accretion rates of pre-main sequence (PMS) stars in the cluster Trumpler 14 (Tr 14) in the Carina Nebula. Using optical...

    Mass constraints to Sco X-1 from Bowen fluorescence and deep near-infrared spectroscopy
    More than 50 years after the dawn of X-ray astronomy, the dynamical parameters of the prototypical X-ray binary Sco X-1 are still unknown. We combine a Monte...

    Mass Ratio Determination from H α Lines in Black Hole X-Ray Transients
    We find that the mass ratio q in quiescent black hole (BH) X-ray transients is tightly correlated with the ratio of the double-peak separation (DP) to the full...
