    Physical constraints on the central mass and baryon content of satellite galaxies
    Recent analysis of the Milky Way's satellite galaxies reveals that these objects share a common central mass density, even though their luminosities range over...

    Physical limits to the validity of synthesis models. The Lowest Luminosity Limit
    In this paper we establish a necessary condition for the application of stellar population synthesis models to observed star clusters. Such a condition is...

    Physical Parameters and Classification of Eight Galactic Nuclei from the Second Byurakan Survey
    Accurate estimates of spectral parameters are essential to investigate the physical conditions in active galactic nuclei (AGNs). In particular, intrinsic...

    Physical parameters of red supergiants in dwarf irregular galaxies in the Local Group
    Context. Increasing the statistics of evolved massive stars in the Local Group enables investigating their evolution at different metallicities. During the late...

    Physical Properties of a Coma-analog Protocluster at z = 6.5
    We present evidence for the discovery of a protocluster of starburst galaxies (Lyα emitters, or LAEs) near the end of the epoch of reionization. The recent...

    Physical Properties of Lyα Emitters at z ~ 0.3 from UV-to-FIR Measurements
    The analysis of the physical properties of low-redshift Lyα emitters (LAEs) can provide clues in the study of their high-redshift analogs. At z ~ 0.3, LAEs are...

    Physical properties of simulated galaxy populations at z = 2 - I. Effect of metal-line cooling and feedback from star formation and AGN
    We use hydrodynamical simulations from the OverWhelmingly Large Simulations (OWLS) project to investigate the dependence of the physical properties of galaxy...

    Physical properties of superbubbles in the Antennae galaxies
    Mass outflow generated by the dynamical feedback from massive stars is currently a topic of great interest. Using a purpose-developed analysis technique, and...
