We report on the characteristics and design details of the Medium Scale Anisotropy Measurement (MSAM), a millimeter-wave, balloon-borne telescope that has been used to observe anisotropy in the Cosmic Microwave Background Radiation (CMBR) on 0. 5 angular scales. The gondola is capable of determining and maintaining absolute orientation to a few arcminutes during a one-night flight. Emphasis is ...

We review the role of the temperature anisotropies and polarization of the cosmic microwave background (CMB) radiation in constraining the cosmological model. We put particular emphasis on the major milestones that have been passed, and CMB constraints on early-universe physics. We also look ahead, surveying what we hope to learn from the next generation of instruments targeting the small-scale...

I’m a third year Ph.D. student in the Physics department working for Adrian Lee. I work on the data analysis pipeline for the POLARBEAR Cosmic Microwave Background (CMB) experiment and I am interested in the computational problems posed by the size and complexity of the datasets that will be produced by the next generation of CMB experiments. I’m also willing to work on something completely unr...

The acceleration of the expansion of the universe has deep implications for structure formation, the composition of the universe, and its fate. Roughly 70% of the energy density is in a dark energy, whose nature remains unknown. Mapping the expansion history through supernovae, mapping the geometry of the universe and formation of structure through redshift surveys, and mapping the distance to ...

The acceleration of the cosmic expansion may be due to a new component of physical energy density or a modification of physics itself. Mapping the expansion of cosmic scales and the growth of large scale structure in tandem can provide insights to distinguish between the two origins. Using Minimal Modified Gravity (MMG)—a single parameter gravitational growth index formalism to parametrize modi...

Ideas of Statistical Physics are very relevant for cosmic structures especially considering that the field is undergoing a period of exceptional development with many new data appearing on a monthly basis. In the past years we have focused mostly on galaxy distributions and their statistical properties. This led to an interesting debate which will be resolved by the next generation of data in a...

We perform a new study of future sensitivities of galaxy redshift surveys to the free-streaming effect caused by neutrino masses, adding the information on cosmological parameters from measurements of primary anisotropies of the cosmic microwave background (CMB). Our reference cosmological scenario has nine parameters and three different neutrino masses, with a hierarchy imposed by oscillation ...

The next generation low-frequency radio telescopes may probe cosmological models by means of observations of the cosmic microwave background (CMB). I discuss the prospects for observations of CMB imprints — recombination lines from the epoch of recombination, μ distortions and angular temperature anisotropies — at low frequencies. A future low-frequency radio telescope, like the proposed SKA, m...

Over the past few years, rapid advances in wireless broadband networks have been driving the evolution of communication and network technologies towards next generation omnipresent computing environments. If a mobile station velocity is high and its movement pattern is irregular, unnecessary handovers likely occur more frequently, and then a seamless handover algorithm between heterogeneous wir...
