Disordered biopolymer filament bundles: Topological defects and kinks
Valentin M. Slepukhin, Maximilian J. Grill, Qingda Hu +3
Bundles of stiff filaments are ubiquitous in the living world, found both in the cytoskeleton and in the extracellular medium. These bundles are typically held together by smaller…
Fabrication Of Economical Signal Amplified Vibrating Sample Magnetometer With Spiral Designed Detector
Aditya Dash, Rabindra Sarkar, Abel Mathew +1
The design and fabrication of a cost-effective vibrating sample magnetometer are explained. Improvement in the detected signal can be obtained using an operational amplifier circui…
Low-redshift quasars in the SDSS Stripe 82 II: associated companion galaxies and signature of star formation
Maria Babakhanyan Stone, Daniela Bettoni, Renato Falomo +4
We present optical spectroscopy of the close companions of 22 low redshift (z<0.5) quasars (QSO) selected from a larger sample of QSO in the SDSS Stripe82 region for which both the…
A search for variable subdwarf B stars in TESS Full Frame Images -- I. Variable objects in the southern ecliptic hemisphere
S. K. Sahoo, A. S. Baran, S. Sanjayan +1
We report the results of our search for pulsating subdwarf B stars in Full Frame Images, sampled at 30 min cadence and collected during Year 1 of the TESS mission. Year 1 covers mo…
Physical properties of the ambient medium and of dense cores in the Perseus star-forming region derived from Herschel Gould Belt Survey observations
