Numerical Simulations of Turbulent Molecular Clouds Regulated by Radiation Feedback Forces II: Radiation-Gas Interactions and Outflows
Sudhir Raskutti, Eve C. Ostriker, M. Aaron Skinner
Momentum deposition by radiation pressure from young, massive stars may help to destroy molecular clouds and unbind stellar clusters by driving large-scale outflows. We extend our…
Numerical Simulations of Turbulent, Molecular Clouds Regulated by Radiation Feedback Forces I: Star Formation Rate and Efficiency
Sudhir Raskutti, Eve C. Ostriker, M. Aaron Skinner
Radiation feedback from stellar clusters is expected to play a key role in setting the rate and efficiency of star formation in giant molecular clouds (GMCs). To investigate how ra…
The Stellar Haloes of Massive Elliptical Galaxies III: Kinematics at Large Radius
Sudhir Raskutti, Jenny Greene, Jeremy Murphy
We present a 2D kinematic analysis out to ~2-5 effective radii (Re) of 33 massive elliptical galaxies with stellar velocity dispersions larger than 150 km/s. Our observations were…
Multi-Epoch High-Spectral-Resolution Observations of Neutral Sodium in 14 Type Ia Supernovae
A. Sternberg, A. Gal Yam, J. D. Simon +16
One of the main questions concerning Type Ia supernovae is the nature of the binary companion of the exploding white dwarf. A major discriminant between different suggested models…
The Stellar Halos of Massive Elliptical Galaxies II: Detailed Abundance Ratios at Large Radius
Jenny E Greene, Jeremy D Murphy, Genevieve J Graves +4
We study the radial dependence in stellar populations of 33 nearby early-type galaxies with central stellar velocity dispersions sigma* > 150 km/s. We measure stellar population pr…
The Structure of Reionization in Hierarchical Galaxy Formation Models
Han-Seek Kim, J. Stuart B. Wyithe, Sudhir Raskutti +2
Understanding the epoch of reionization and the properties of the first galaxies represents an important goal for modern cosmology. The structure of reionization, and hence the obs…
Thermal constraints on the reionisation of hydrogen by population-II stellar sources
Sudhir Raskutti, James S. Bolton, J. Stuart B. Wyithe +1
Measurements of the intergalactic medium (IGM) temperature provide a potentially powerful constraint on the reionisation history due to the thermal imprint left by the photo-ionisa…
Improved measurements of the intergalactic medium temperature around quasars: possible evidence for the initial stages of He-II reionisation at z~6
James S. Bolton, George D. Becker, Sudhir Raskutti +3
We present measurements of the intergalactic medium (IGM) temperature within ~5 proper Mpc of seven luminous quasars at z~6. The constraints are obtained from the Doppler widths of…
