The Green Bank North Celestial Cap Survey. VII. 12 New Pulsar Timing Solutions
Joseph K. Swiggum, Ziggy Pleunis, Emilie Parent +22
We present timing solutions for 12 pulsars discovered in the Green Bank North Celestial Cap (GBNCC) 350 MHz pulsar survey, including six millisecond pulsars (MSPs), a double neutro…
Inflation using a triplet of Antisymmetric tensor fields
Abhijith Ajith, Sukanta Panda
We study an inflation model driven by a triplet of antisymmetric tensor fields, with minimal and nonminimal couplings to gravity. First, we show that the presence of a triplet of a…
Soft and Collinear Limits in Supergravity using Double Copy Formalism
Nabamita Banerjee, Tabasum Rahnuma, Ranveer Kumar Singh
It is known that supergravity is dual to super Yang-Mills (SYM) via the double copy relation. Using the explicit relation between scattering amplitu…
Detection of Dipole Modulation in CMB Temperature Anisotropy Maps from WMAP and Planck using Artificial Intelligence
Md Ishaque Khan, Rajib Saha
Breakdown of rotational invariance of the primordial power spectrum manifests in the statistical anisotropy of the observed Cosmic Microwave Background (CMB) radiation. Hemispheric…
Constant-Roll Inflation in modified gravity model using Palatini Formalism
Sukanta Panda, Arun Rana, Rahul Thakur
In this work, we study a constant-roll inflationary model in the Palatini formalism using modified gravity. Here our action consists a non-minimal coupling of a scalar field wi…
Gravitational wave signatures of phase transition from hadronic to quark matter in isolated neutron stars and binaries
Ritam Mallick
The fundamental constituent of matter at high temperature and density has intrigued physicists for quite some time. Recent results from heavy-ion colliders have enriched the Quantu…
Morphological Parameters and Associated Uncertainties for 8 Million Galaxies in the Hyper Suprime-Cam Wide Survey
Aritra Ghosh, C. Megan Urry, Aayush Mishra +10
We use the Galaxy Morphology Posterior Estimation Network (GaMPEN) to estimate morphological parameters and associated uncertainties for million galaxies in the Hyper Supr…
Photometric identification of compact galaxies, stars and quasars using multiple neural networks
Siddharth Chaini, Atharva Bagul, Anish Deshpande +4
We present MargNet, a deep learning-based classifier for identifying stars, quasars and compact galaxies using photometric parameters and images from the Sloan Digital Sky Survey (…
Time-reversal symmetry breaking in superconducting low-carrier-density quasi-skutterudite Lu3Os4Ge13
A. Kataria, J. A. T. Verezhak, O. Prakash +6
The complex structure of the Remeika phases, the intriguing quantum states they display, and their low carrier concentrations are a strong motivation to study the nature of their s…
Effect of topological length on Bound states signatures in a Topological nanowire
Dibyajyoti Sahu, Vipin Khade, Suhas Gangadharaiah
Majorana bound states (MBS) at the end of nanowires have been proposed as one of the most important candidate for the topological qubits. However, similar tunneling conductance fea…
JT gravity from holographic reduction of 3D asymptotically flat spacetime
Arindam Bhattacharjee, Muktajyoti Saha
We attempt to understand the CFT structure underlying (2+1)D gravity in flat spacetime via dimensional reduction. We observe that under superrotation, the hyperbolic (and dS$_2…
Generalized Orthogonal Measures on the Space of Unital Completely Positive Maps
Angshuman Bhattacharya, Chaitanya J. Kulkarni
A classical result by Effros connects the barycentric decomposition of a state on a C*-algebra to the disintegration of the GNS representation of the state with respect to an ortho…
Barycentric decompositions in the space of weak expectations
Angshuman Bhattacharya, Chaitanya J. Kulkarni
The space of weak expectations for a given representation of a (unital) separable C*-algebra is a compact convex set of (unital) completely positive maps in the BW topology, when i…
Decomposable Weak Expectations
Angshuman Bhattacharya, Chaitanya J. Kulkarni
In this article we define a special class of weak expectations for a representation of a separable unital C*-algebra, called decomposable weak expectation. We give necessary and su…
Reconstruction of full sky CMB and modes spectra removing -to- leakage from partial sky using deep learning
Srikanta Pal, Rajib Saha
Incomplete sky analysis of cosmic microwave background (CMB) polarization spectra poses a major problem of leakage between - and -modes. We present a machine learning approac…
High-yield exfoliation of MoS2 nanosheets by a novel spray technique and the importance of soaking and surfactants
Suvigya Kaushik, Siva Sankar Nemala, Mukesh Kumar +7
Liquid-phase exfoliation of two-dimensional materials is very attractive for large-scale applications. Although used extensively, isolating MoS2 layers (<10) with high efficiency i…
