A novel chiral spin texture: Antiferromagnetic Skyrmionium
Mona Minakshee Manjaree Bhukta, Abhilash Mishra, Gajanan Pradhan +3
Exotic spin textures viz. chiral domain wall, vortices, skyrmion, skyrmionium, etc. have recently emerged as active field of research because of their potential applications in hig…
Detecting primordial gravitational waves with circular polarization of the redshifted 21 cm line: II. Forecasts
Abhilash Mishra, Christopher M. Hirata
In the first paper of this series, we showed that the CMB quadrupole at high redshifts results in a small circular polarization of the emitted 21 cm radiation. In this paper we for…
Detecting primordial gravitational waves with circular polarization of the redshifted 21 cm line: I. Formalism
Christopher M. Hirata, Abhilash Mishra, Tejaswi Venumadhav
We propose a new method to measure the tensor-to-scalar ratio using the circular polarization of the 21 cm radiation from the pre-reionization epoch. Our method relies on the s…
A new probe of magnetic fields in the pre-reionization epoch: II. Detectability
Vera Gluscevic, Tejaswi Venumadhav, Xiao Fang +3
In the first paper of this series, we proposed a novel method to probe large-scale intergalactic magnetic fields during the cosmic Dark Ages, using 21-cm tomography. This method re…
New probe of magnetic fields in the prereionization epoch. I. Formalism
Tejaswi Venumadhav, Antonija Oklopcic, Vera Gluscevic +2
We propose a method of measuring extremely weak magnetic fields in the intergalactic medium prior to and during the epoch of cosmic reionization. The method utilizes the Larmor pre…
Inflationary Freedom and Cosmological Neutrino Constraints
Roland de Putter, Eric V. Linder, Abhilash Mishra
The most stringent bounds on the absolute neutrino mass scale come from cosmological data. These bounds are made possible because massive relic neutrinos affect the expansion histo…
