Time Delay Analysis of the Lensed Quasar SDSS J1001+5027
Amir Aghamousa, Arman Shafieloo
We modify the algorithm we proposed before in Aghamousa & Shafieloo (2015) on time delay estimation of the strong lens systems incorporating weighted cross-correlation and weighted…
Unveiling acoustic physics of the CMB using nonparametric estimation of the temperature angular power spectrum for Planck
Amir Aghamousa, Arman Shafieloo, Mihir Arjunwadkar +1
Estimation of the angular power spectrum is one of the important steps in Cosmic Microwave Background (CMB) data analysis. Here, we present a nonparametric estimate of the temperat…
Fast and Reliable Time Delay Estimation of Strong Lens Systems Using Method of Smoothing and Cross-Correlation
Amir Aghamousa, Arman Shafieloo
The observable time delays between the multiple images of strong lensing systems with time variable sources can provide us with some valuable information to probe the expansion his…
Strong Lens Time Delay Challenge: II. Results of TDC1
Kai Liao, Tommaso Treu, Phil Marshall +23
We present the results of the first strong lens time delay challenge. The motivation, experimental design, and entry level challenge are described in a companion paper. This paper…
Nonparametric Forecasts of the CMB Angular Power Spectra for the Planck Mission
Amir Aghamousa, Mihir Arjunwadkar, Tarun Souradeep
The Planck mission, designed for making measurements of the cosmic microwave background (CMB) radiation with unprecedented accuracy and angular resolution, is expected to release i…
From Nonparametric Power Spectra to Inference About Cosmological Parameters: A Random Walk in the Cosmological Parameter Space
Amir Aghamousa, Mihir Arjunwadkar, Tarun Souradeep
What do the data, as distinguished from cosmological models, tell us about cosmological parameters that determined the model of the universe? In this paper, we address this questio…
Evolution of the CMB Power Spectrum Across WMAP Data Releases: A Nonparametric Analysis
Amir Aghamousa, Mihir Arjunwadkar, Tarun Souradeep
Using a nonparametric function estimation methodology, we present a comparative analysis of the WMAP 1-, 3-, 5-, and 7-year data releases for the CMB angular power spectrum with re…
