Polarimetric and photometric investigation of a dark globule LDN 1225: distance, extinction law, and magnetic fields
Chakali Eswaraiah, Shih-Ping Lai, Yuehui Ma +7
We present the results based on the optical -band polarization observations of 280 stars distributed towards the dark globule LDN\,1225. {\it Gaia} data release 2 parallaxes alo…
Role of time scales and topology on the dynamics of complex networks
Kajari Gupta, G. Ambika
The interplay between time scales and structural properties of complex networks of nonlinear oscillators can generate many interesting phenomena, like amplitude death, cluster sync…
Higher order spectral analysis of ECG signals
Yamini Kotriwar, Sneha Kachhara, K. P. Harikrishnan +1
Higher Order Spectral (HOS) analysis is often applied effectively to analyze many bio-medical signals to detect nonlinear and non-Gaussian processes. One of the most basic HOS meth…
Link deletion in directed complex networks
G. Kashyap, G. Ambika
We present a systematic and detailed study of the robustness of directed networks under random and targeted removal of links. We work with a set of network models of random and sca…
Completely Uncoupled User Association Algorithms for State Dependent Wireless Networks
S. Ramakrishnan, Venkatesh Ramaiyan, K. P. Naveen
We study a distributed user association algorithm for a heterogeneous wireless network with the objective of maximizing the sum of the utilities (on the received throughput of wire…
The Planck Cold Clump G108.37-01.06: A Site of Complex Interplay between H II Regions, Young Clusters and Filaments
Somnath Dutta, Soumen Mondal, Manash R Samal +1
The {\it Planck} Galactic Cold Clumps (PGCCs) are the possible representations of the initial conditions and the very early stages of star formation. With an objective to understan…
Models of representations and Langlands functoriality
Arnab Mitra, Eitan Sayag
In this article we explore the interplay between two generalizations of the Whittaker model, namely the Klyachko models and the degenerate Whittaker models, and two functorial cons…
Role of system size on freezeout conditions extracted from transverse momentum spectra of hadrons
Ajay Kumar Dash, Ranbir Singh, Sandeep Chatterjee +2
The data on hadron transverse momentum spectra in different centrality classes of p+Pb collisions at TeV has been analysed to extract the freezeout hypersurf…
Mass modelling of a superthin galaxy, FGC1540
Sushma Kurapati, Arunima Banerjee, Jayaram N. Chengalur +4
We present high resolution H{\sc i} 21cm Giant Meterwave Radio Telescope (GMRT) observations of the superthin galaxy FGC1540 with a spatial resolution of 10 8 and…
Absolute cross-sections of fragment negative ions in electron collisions with difluoromethane
Dipayan Chakraborty, Dhananjay Nandi
Dissociative electron attachment (DEA) and ion-pair dissociation (IPD) processes of Difluoromethane (CHF) have been studied in the incident electron energy range 0 to 45 eV…
Characterization of Stellar and Substellar Members in the Coma Berenices Star Cluster
Shih-Yun Tang, W. P. Chen, P. S. Chiang +3
We have identified stellar and substellar members in the nearby star cluster Coma Berenices, using photometry, proper motions, and distances of a combination of 2MASS, UKIDSS, URAT…
Minkowski Tensors in Three Dimensions - Probing the Anisotropy Generated by Redshift Space Distortion
Stephen Appleby, Pravabati Chingangbam, Changbom Park +2
We apply the Minkowski tensor statistics to three dimensional Gaussian random fields. Minkowski tensors contain information regarding the orientation and shape of excursion sets, t…
Fractal Measures and Nonlinear Dynamics of Overcontact Binaries
Sandip V. George, R. Misra, G. Ambika
Overcontact binary stars are systems of two stars where the component stars are in contact with each other. This implies that they share a common envelope of gas. In this work we s…
YSO jets in the Galactic Plane from UWISH2: V - Jets and Outflows in M17
Manash R. Samal, Wen-Ping Chen, Michihiro Takami +2
Jets and outflows are the first signposts of stellar birth. Emission in the H2 1-0S(1) line at 2.122 micron is a powerful tracer of shock excitation in these objects. Here we prese…
Evolution of Late-type Galaxies in a Cluster Environment: Effects of High-speed Multiple Encounters with Early-type Galaxies
Jeong-Sun Hwang, Changbom Park, Arunima Banerjee +1
Late-type galaxies falling into a cluster would evolve being influenced by the interactions with both the cluster and the nearby cluster member galaxies. Most numerical studies, ho…
Full Band All-sky Search for Periodic Gravitational Waves in the O1 LIGO Data
The LIGO Scientific Collaboration, the Virgo Collaboration, B. P. Abbott +1099
We report on a new all-sky search for periodic gravitational waves in the frequency band 475-2000 Hz and with a frequency time derivative in the range of [-1.0e-8, +1e-9] Hz/s. Pot…
Optical Photometric Variable Stars towards the Galactic \hii region NGC 2282
Somnath Dutta, Soumen Mondal, Santosh Joshi +3
We report here CCD -band time-series photometry of a young (25 Myr) cluster NGC 2282 to identify and understand the variability of pre-main-sequence (PMS) stars. The -band…
A Search for Tensor, Vector, and Scalar Polarizations in the Stochastic Gravitational-Wave Background
The LIGO Scientific Collaboration, the Virgo Collaboration, B. P. Abbott +1097
The detection of gravitational waves with Advanced LIGO and Advanced Virgo has enabled novel tests of general relativity, including direct study of the polarization of gravitationa…
