-
(NURIS; Energetic Cosmos Laboratory, 2019-04-02)Cosmic Microwave Background temperature and polarization anisotropies from Planck have estimated lower value of the optical depth to reionization (τ) compared to WMAP.
-
(NURIS; Energetic Cosmos Laboratory, 2019-01-10)We identify a binary black hole (BBH) merger that appears to be multiply lensed by an intervening galaxy. The LIGO/Virgo events GW170809 and GW170814 have indistinguishable waveforms separated by 5 days, and overlap on the ...
-
(NURIS; Energetic Cosmos Laboratory, 2018-07-14)We explore the constraints on the history of reionization from Planck 2015 CosmicMicrowave Background (CMB) data and we derive the forecasts for future CMB observations.We consider a class of monotonic histories of ...
-
(2017-01-31)Abstract Cosmological measurements of both the expansion history and growth history have matured, and the two together provide an important test of general relativity. We consider their joint evolutionary track, showing ...
-
(American Physical Society, 2016-12-02)We use baryon acoustic oscillation and redshift space distortion from the completed Baryon Oscillation Spectroscopic Survey, corresponding to data release 12 of the Sloan Digital Sky Survey, combined sample analysis in ...
-
(NURIS; Energetic Cosmos Laboratory, 2018-03-21)We explore freezing dark energy, where the evolution of the field approaches that of a cosmological constant at late times. We propose two general, two-parameter forms to describe the class of freezing field models, in ...
-
(NURIS; Energetic Cosmos Laboratory, 2018-09-05)Cosmic growth of large scale structure probes the entire history of cosmic expansion and gravitational coupling. To get a clear picture of the effects of modification of gravity we consider a deviation in the coupling ...
-
(American Physical Society, 2017-07-19)Dynamical dark energy has been recently suggested as a promising and physical way to solve the 3 sigma tension on the value of the Hubble constant H0 between the direct measurement of Riess et al. (2016) (R16, hereafter) ...
-
(NURIS; Energetic Cosmos Laboratory, 2017-05-08)We consider methods for improving the estimation of constraints on a high-dimensional parameter space with a computationally expensive likelihood function. In such cases Markov chain Monte Carlo (MCMC) can take a long time ...
-
(American Physical Society, 2017-12-22)Radiation from accelerating mirrors in a Minkowski spacetime provides insights into the nature of horizons, black holes, and entanglement entropy. We introduce new, simple, symmetric and analytic moving mirror solutions ...
-
(NURIS; Energetic Cosmos Laboratory, 2017-12-11)We constrain the history of reionization using the data from Planck 2015 Cosmic Microwave Background (CMB) temperature and polarization anisotropy observations. We also use prior constraints on the reionization history at ...
-
(NURIS; Energetic Cosmos Laboratory, 2017-09-25)Adding to our previous method for dealing with gravitational modifications at redshiftz&3through a single parameter, we investigate treatment of lower redshift modifications to linear growth observables. We establish sub ...
-
Probing features in inflaton potential and reionization history with future CMB space observations (NURIS; Energetic Cosmos Laboratory, 2018-03-04)We consider the prospects of probing features in the primordial power spectrum with future Cosmic Microwave Background (CMB) polarization measurements. In the scope of the inflationary scenario, such features in the spectrum ...
-
(American Physical Society, 2018-02-23)Taking the Planck cosmic microwave background data and the more direct Hubble constant measurement data as unaffected by systematic offsets, the values of the Hubble constant $H_0$ interpreted within the $\Lambda$CDM ...
-
(NURIS; Energetic Cosmos Laboratory, 2017-11-27)The analogy between black hole radiation and accelerating mirror radiation (the dynamical Casimir effect) is particularly strong for mirror trajectories giving rise to a constant thermal flux of particles. We present new ...
-
(NURIS; Energetic Cosmos Laboratory, 2018-01-04)A subclass of the Horndeski modified gravity theory we call No Slip Gravity has particularly interesting properties: 1) a speed of gravitational wave propagation equal to the speed of light, 2) equality between the effective ...
-
(NURIS; Energetic Cosmos Laboratory, 2018-02-13)Cosmic spatial curvature is a fundamental geometric quantity of the Universe. We investigate a model independent, geometric approach to measure spatial curvature directly from observations,without any derivatives of data. ...
-
(NURIS; Energetic Cosmos Laboratory, 2018-02-14)Gravitational waves can be focussed by the gravity of an intervening galaxy, just like light, thereby magnifying binary merging events in the far Universe. High magnification by galaxies is found to be responsible for the ...
-
(NURIS; Energetic Cosmos Laboratory, 2018-03-01)The possibility of linking inflation and late cosmic accelerated expansion using the α-attractor models has received increasing attention due to their physical motivation. In the early universe, α-attractors provide an ...
-
(NURIS; Energetic Cosmos Laboratory, 2018-05-01)Self tuning is one of the few methods for dynamically cancelling a large cosmological constantand yet giving an accelerating universe. Its drawback is that it tends to screen all sources of energydensity, including matter. ...
