    Massive Relic Galaxies Challenge the Co-evolution of Super-massive Black Holes and Their Host Galaxies
    We study a sample of eight massive galaxies that are extreme outliers (3–5σ) in the {M}\bullet ‑ Mbulge local scaling relation. Two of these galaxies are...

    MASTER Optical Polarization Variability Detection in the Microquasar V404 Cyg/GS 2023+33
    On 2015 June 15, the Swift space observatory discovered that the Galactic black hole candidate V404 Cyg was undergoing another active X-ray phase, after 25...

    Matter ejections behind the highs and lows of the transitional millisecond pulsar PSR J1023+0038
    Transitional millisecond pulsars are an emerging class of sources that link low-mass X-ray binaries to millisecond radio pulsars in binary systems. These...

    Measuring masses in low mass X-ray binaries via X-ray spectroscopy: the case of MXB 1659-298
    The determination of fundamental parameters in low-mass X-ray binaries (LMXBs) typically relies on measuring the radial velocity curve of the companion star...

    Measuring Microlensing Using Spectra of Multiply Lensed Quasars
    We report on a program of spectroscopic observations of gravitationally lensed QSOs with multiple images. We seek to establish whether microlensing is occurring...

    Merging in the common envelope and the origin of early R-type stars
    Context. Binary systems experiencing one or two common envelope episodes during the red giant branch or the Hertzsprung gap phases can produce a single star...

    Microlensing analysis of 14.5-year light curves in SDSS J1004+4112: Quasar accretion disk size and intracluster stellar mass fraction
    Context. The gravitational lens system SDSS J1004+4112 was the first known example of a quasar lensed by a galaxy cluster. The interest in this system has been...

    Milliarcsec-scale radio emission of ultraluminous X-ray sources: steady jet emission from an intermediate-mass black hole?
    The origin of the high X-ray luminosities of most ultraluminous X-ray sources (ULXs) still remains poorly understood. Most of the scenarios proposed to explain...

    Millihertz Quasi-periodic Oscillations and Thermonuclear Bursts from Terzan 5: A Showcase of Burning Regimes
    We present a comprehensive study of the thermonuclear bursts and millihertz quasi-periodic oscillations (mHz QPOs) from the neutron star (NS) transient and 11...
