Probing X-ray photoevaporative winds through their interaction with …

We show that if young low mass stars undergo vigorous X-ray driven disc winds, these may be detected in clusters through their interaction with ionis…

The Signature of Galactic Tides in Local Group Dwarf Spheroidals

(Abridged) We use N-body simulations to explore the effects of tidal stripping on the structure of dwarf spheroidal galaxies (dSphs). We model dSphs …

Detection of a QPO in 5 XMM-Newton observations of RE J1034+396

The X-ray quasi-periodic oscillation (QPO) at $\sim 2.6 \times 10^{-4}$ Hz in RE J1034+396 has been robustly observed in the 0.2-10 keV band of one $…

In the thick of it: metal-poor disc stars in RAVE

By selecting in the RAVE-DR4 survey the stars located between 1 and 2 kpc above the Galactic plane, we question the consistency of the simplest three…

Debris from terrestrial planet formation: the Moon-forming collision

We study the evolution of debris created in the giant impacts expected during the final stages of terrestrial planet formation. The starting point is…

Gaia Benchmark stars and their twins in the Gaia-ESO Survey

The Gaia benchmark stars are stars with very precise stellar parameters that cover a wide range in the HR diagram at various metallicities. They are …

ALMA observations of the multiplanet system 61 Vir: What lies outside…

A decade of surveys has hinted at a possible higher occurrence rate of debris discs in systems hosting low mass planets. This could be due to common …

Improved time-frequency analysis of extreme-mass-ratio inspiral signa…

The planned Laser Interferometer Space Antenna (LISA) is expected to detect gravitational wave signals from ~100 extreme-mass-ratio inspirals (EMRIs)…

Characterizing gravito-turbulence in 3D: turbulent properties and s…

We have investigated the properties of gravito-turbulent discs in 3D using high-resolution shearing-box simulations. For large enough domain sizes, $…

Dynamical Models of Elliptical Galaxies -- I. Simple Methods

We study dynamical models for elliptical galaxies, deriving the projected kinematic profiles in a form that is valid for general surface-brightness p…

A NuSTAR observation of disk reflection from close to the neutron sta…

Studying the reflection of X-rays off the inner edge of the accretion disk in a neutron star low-mass X-ray binary, allows us to investigate the accr…

Exactly Solvable and Integrable Systems

A New Superintegrable Hamiltonian

We identify a new superintegrable Hamiltonian in 3 degrees of freedom, obtained as a reduction of pure Keplerian motion in 6 dimensions. The new Hami…

Bianchi Model CMB Polarization and its Implications for CMB Anomalies

We derive the CMB radiative transfer equation in the form of a multipole hierarchy in the nearly-Friedmann-Robertson-Walker limit of homogeneous, but…

Neutron star crust cooling in the Terzan 5 X-ray transient Swift J1…

When neutron stars reside in transient X-ray binaries, their crustal layers become heated during accretion outbursts and subsequently cool in quiesce…

Super-Eddington Accretion onto the Neutron Star NGC 7793 P13: Broadba…

We present a detailed, broadband X-ray spectral analysis of the ULX pulsar NGC 7793 P13, a known super-Eddington source, utilizing data from the $XMM…

The Milky Way stellar halo out to 40 kpc : Squashed, broken but smooth

We introduce a new maximum likelihood method to model the density profile of Blue Horizontal Branch and Blue Straggler stars and apply it to the Sloa…

The Optical Gravitational Lensing Experiment. The OGLE-III Catalog of…

The eleventh part of the OGLE-III Catalog of Variable Stars (OIII-CVS) contains 16836 RR Lyr stars detected in the OGLE fields toward the Galactic bu…

The observations presented in this paper were made with the Giant Metrewave Radio Telescope (GMRT). The GMRT is operated by the National Center for Radio Astrophysics of the Tata Institute of Fundamental Research.

Baryonic Tully-Fisher Relation for Extremely Low Mass Galaxies

We study Tully-Fisher relations for a sample that combines extremely faint (M_B > -14.0) galaxies along with bright (i.e. L_*) galaxies. Accurate (~ …

Cosmological Constraints on Dissipative Models of Inflation

(Abridged) We study dissipative inflation in the regime where the dissipative term takes a specific form, \Gamma=\Gamma(\phi), analyzing two models i…
