    Two white dwarfs in ultrashort binaries with detached, eclipsing, likely sub-stellar companions detected by K2
    Using data from the extended Kepler mission in K2 Campaign 10, we identify two eclipsing binaries containing white dwarfs with cool companions that have...

    Two-dimensional line-strength maps in three well-studied early-type galaxies
    Integral field spectroscopy has been obtained for the nuclear regions of three large, well-studied, early-type galaxies. From these spectra we have obtained...

    Two-dimensional spectroscopy of the Seyfert galaxies NGC 5728 and 4151 in the [OIII] lambdalambda4959, 5007 and Hα spectral ranges
    We have performed two-dimensional spectroscopy of the Seyfert galaxies NGC 5728 and 4151 in the 4500-7500A spectral range. The data (especially the [OIII]...

    Type I X-ray bursts and burst oscillations in the accreting millisecond X-ray pulsar IGR J17511-3057
    We report the discovery of burst oscillations at the spin frequency in ten thermonuclear bursts from the accreting millisecond X-ray pulsar (AMXP) IGR J17511...

    Type I X-ray bursts, burst oscillations and kHz quasi-periodic oscillations in the neutron star system IGRJ17191-2821
    We present a detailed study of the X-ray energy and power spectral properties of the neutron star transient IGRJ17191-2821. We discovered four instances of...

    Type Ia supernovae with and without blueshifted narrow Na I D lines - how different is their structure?
    In studies on intermediate- and high-resolution spectra of Type Ia supernovae (SNe Ia), some objects exhibit narrow Na I D absorptions often blueshifted with...

    Ubiquitous seeding of supermassive black holes by direct collapse
    We study for the first time the environment of massive black hole (BH) seeds (˜104-5 M⊙) formed via the direct collapse of pristine gas clouds in massive haloes...

    UBRI photometry of globular clusters in the Leo group galaxy NGC 3379
    We present wide-area UBRI photometry for globular clusters around the Leo group galaxy NGC 3379. Globular cluster candidates are selected from their B-band...

    UBV(RI)C photometry of the open clusters Be 15, Be 80 and NGC 2192
    The three open clusters Be 15, Be 80 and NGC 2192 have been observed using CCD UBV(RI)C photometry at the San Pedro Mártir Observatory, México within the...
