Research

My research is in experimental general relativity, focusing mostly upon gravitational wave detection with the LIGO Scientific Collaboration. Topics I devote particular attention to are:

* Search for gravitational wave bursts.
photo, micho - Search for gravitational wave bursts from optical supernovae. When a sufficiently massive star dies, it can result in a massive explosion called a supernova. For decades we have been able to see the electromagnetic results of these explosions, but now, with the help of the data from interferometers, we hope to generate evidence for the gravitational waves emitted by these explosions and understand better their physical mechanism. We are developing an alghorithm that allows one to analyze weeks of interferometer data around the recorded time of the supernova optical signatures. The tool is to modify an existing algorithm currently used for all-sky searches of un-modelled GW transients, Coherent Waveburst. This code combines the signals from different interferomenters in a coherent way. We are customizing it to only be sensitive to signals from directions consistent with the supernova location, and track that location during deveral sideereal days. This approach is motivated by the desire to increase the sensitivity and solve one of the problems in observing GWs from optical supernovae: the large uncertainty in the exact time of emission of the GWs. The observed optical signal is not usually the beginning of the supernova light curve which might not be the exact time of emission of the gravitational wave. More explictly, if the mechanism that generates these waves is the acoustic bounce of the expanding gasses off the solid core it can reinitialize the fusion process and the visible explosion. This bounce occurs within seconds of the explosion, but because of the significant turmoil of these explosions, it can take up to a day for the first electromagnetic signals to escape the explosion. Then the fact that the first EM emissions are rarely observed directly can increase the time uncertainty to weeks. In this search weanalyze supernova events recorded by astronomers during the S6 data run. The current research page can be found in Research student Lex Corpuz's Page.
. - Another ongoing activity to improve the detection of gravitational wave transients (GWT) is the development of distributional tests methodologies for the detection of GWT.

* Estimation of parameters from gravitational wave transients and other high precision measurements.
High precision measurements in modern astrophysics and cosmology have fantastic goals that range from observing the properties of the cosmic microwave background to listen to the symphonies of the universe recorded in the perturbations of its metric. However how many of these effects are observable by LIGO? where should we focus brain and financial resources? The methodology described in Phys.Rev.D81:124048,2010 and Phys.Rev. D84 (2011) 104020 extend the standard results on parameter estimation based on the Fisher information matrix allow for a deeper understanding of the errors in estimating parameters from weak signals. The tool are asymptotic expansions inspired by the Dyson equation that allow one to calculate analytically the moments of an estimator as inverse powers of the signal to noise ratio (and/or the number of measurements if an experiment allows it). There are several applications of this methodology, for example: -how well can we estimate physical parameters (and the physics attached) and the direction of arrival from gravitational wave transients?
-can we (or will we) be able to distinguish between standard GR and alternative models of gravity?
- will we be able to detect non-Gaussianites in the CMB?

Calibration studies
S5 calibration in LIGO

photo, micho Measurement of the Young modulus of the coatings of LIGO mirrors.
At present, the value of the Young's modulus is probably the least well known parameter determining the Brownian thermal noise of the AdLIGO baseline coatings. Since thermal noise dominates the most sensitive Advanced Ligo Band our lack of knowledge about the Young's modulus is probably the dominant uncertainty in our projections of the Advanced LIGO range. Also, for coating development beyond the initial implementation of Advanced LIGO, the Young's modulus must be measured directly to properly compare different test-coatings. Embry-Riddle is involved in an NSF-funded effort to develop coatings for use in future detector upgrades. setup , pulses


Some of the present and past activities of the ERAU-LIGO group are also summarized here . I also have an ongoing interest in underwater acoustics because there is a lot of data analysis in common between the two. For example you might be interested in listening to the sounds of some gravitational waves here (credits Scott Hughes at MIT).
