  • B-fields and dust in interstellar filaments using dust polarization (BALLAD-POL). III. Grain alignment and disruption mechanisms in G34.43+0.24 using polarization observations from JCMT/POL-2 
    Pravash, Saikhom; Archana Soam; Diep, Pham Ngoc; Hoang, Thiem; Ngoc, Nguyen Bich; Tram, Le Ngoc (American Astronomical Society, 2025-03-10)
    Polarization of starlight and thermal dust emission due to aligned non-spherical grains helps us to trace magnetic field (B-field) morphology in molecular clouds and to study grain alignment mechanisms. In this work, we ...
  • B-fields in Star-forming Region Observations (BISTRO): Magnetic Fields in the Filamentary Structures of Serpens Main 
    Kwon, Woojin; Pattle, Kate; Sadavoy, Sarah; Hull, Charles L. H; Johnstone, Doug; Ward-Thompson, Derek; Francesco, James Di; Koch, Patrick M; Furuya, Ray; Doi, Yasuo; Le Gouellec, Valentin J. M; Hwang, Jihye; Lyo, A. -Ran; Archana Soam; & 138 Co-authors (American Astronomical Society, 2022-02-20)
    We present 850 μm polarimetric observations toward the Serpens Main molecular cloud obtained using the POL-2 polarimeter on the James Clerk Maxwell Telescope as part of the B-fields In STar-forming Region Observations ...
  • B-L cosmic strings and baryogenesis 
    Bhattacharjee, P; Sahu, N; Yajnik, U.A (American Physical Society, 2004-10)
    Cosmic strings arising from breaking of the $U(1)_{B-L}$ gauge symmetry that occurs in a wide variety of unified models can carry zero modes of heavy Majorana neutrinos. Decaying and/or repeatedly self-interacting closed ...
  • Ba+ quadrupole polarizabilities: theory versus experiment 
    Sahoo, B. K; Das, B. P (American Physical Society, 2012-08)
    Three different measurements have been reported for the ground-state quadrupole polarizability in singly ionized barium (Ba+) which disagree with each other. Our calculation of this quantity using the relativistic ...
  • Baby supernovae through the looking glass at long wavelengths 
    Chandra, P; Ray, A (Astronomical Society of India, 2004-09)
    We emphasize the importance of observations of young supernovae in wide radio band. We argue on the basis of observational results that only high- or only low-frequency data is not sufficient to get full physical picture ...
  • Balloon UV experiments for astronomical and atmospheric observations 
    Sreejith, A. G; Mathew, J; Mayuresh, Sarpotdar; Nirmal, K; Ambily, S; Prakash, A; Safonova, M; Murthy, J (SPIE-The International Society for Optical Engineering, 2016-08)
    The ultraviolet (UV) window has been largely unexplored through balloons for astronomy. We discuss here the development of a compact near-UV spectrograph with fiber optics input for balloon flights. It is a modified ...
  • Balloon-borne far-infrared mapping of galactic star forming regions 
    Das, B; Ghosh, S. K; Rengarajan, T. N; Verma, R. P; Iyengar, K. V. K; Tandon, S. N (Astronomical Society of India, 1993)
    Large angular areas (greater than 500 sq arcmin each) covering the three Galactic star forming regions (NGC 2024, OMC-1/OMC-2, and IRAS 06058 + 2138 and its neighborhood) have been mapped in two FIR bands (58 and 150 ...
  • Band-limited integrated scatter measurements on super polished optical mirrors 
    Ventaka, S; Prasad, B. R; Natarajan, V; Kamath, P. U; Kathiravan, S (SPIE-The International Society for Optical Engineering, 2020-08)
    Scattering of light from a surface depends on its microroughness. In general, total integrated scattering of a surface is expressed in terms of root-mean-square microroughness (σrms) using empirical relations. These ...
  • Bangalore chips in for world's largest telescope 
    The Times of India (The Times of India, 2012-09-12)
  • Bangalore eclipsed by a rain cloud 
    DNA (DNA, 2009-07-23)
  • Bangalore scientists experiment in China 
    Deccan Herald (Deccan Herald, 2009-07-23)
  • Bangalore's big leap into universe 
    The Times of Deccan (The Times of Deccan, 1982-09-09)
  • A Bangalorean helped physicist calculate time 
    Kundu, Rhik (The Times of India, 2013-01-02)
    Bangalore: American physicist David J Wineland, who along with French scientist Serge Haroche won the 2012Nobel Prize for his works in quantum physics, has a Bangalore connection. This link, incidentally, contributed ...
  • Bappu's records for institute 
    Indian Express (Indian Express, 1983-08-11)
  • Bappu's statue unveiled in city 
    Deccan Herald (Deccan Herald, 1985-08-11)
  • Bar formation and destruction in the FIRE-2 simulations 
    Ansar, Sioree; Pearson, Sarah; Sanderson, Robyn E; Arora, Arpit; Hopkins, Philip F; Wetzel, Andrew; Cunningham, Emily C; Quinn, Jamie (American Astronomical Society, 2025-01-01)
    The physical mechanisms responsible for bar formation and destruction in galaxies remain a subject of debate. While we have gained valuable insight into how bars form and evolve from isolated idealized simulations, in the ...
  • Bar quenching: Evidence from star-formation-rate indicators 
    George, K; Subramanian, S (EDP Sciences, 2021-07)
    The central regions of star-forming barred spiral galaxies can be devoid of star formation because of the redistribution of gas along the length of the bar. However, there can be gas outside the length of the bar that can ...
  • Bar rejuvenation in S0 galaxies? 
    Barway, Sudhanshu; Saha, Kanak (Oxford University Press on behalf of the Royal Astronomical Society, 2020-07)
    Based on the colour measurements from a multiband, multicomponent 2D decompositions of S0 and spiral galaxies using SDSS images, we found that bars are bluer in S0 galaxies compared to the spiral galaxies. Most of the S0s ...
  • Baryogenesis via leptogenesis in presence of cosmic strings 
    Sahu, N; Bhattacharjee, P; Yajnik, U. A (Elsevier, 2006-09)
    We study the effect on leptogenesis due to B L cosmic strings of a U1 extension of the Standard Model. The disappearance of closed loops of B L cosmic strings can produce heavy right handed neutrinos, N's, whose CP-asymmetric ...
  • Baryonic ecosystem in galaxies (BEINGMgII): I. host galaxies of ultra-strong Mg II absorbers in the Subaru Hyper Suprime-Cam Survey 
    Joshi, Ravi; Das, S; Fumagalli, Michele; Fossati, Matteo; Peroux, Celine; Chaudhary, Reena; Yesuf, Hassen; Ho, Luis C (EDP Sciences, 2025-03)
    Context. We study the galaxies hosting ultra-strong Mg II (USMgII) absorbers at small impact parameters of ∼2″ (5‑20 kpc) spanning a redshift range of 0.4 ≤ z ≤ 1.7 using deep high-resolution images from the Hyper Suprime-Cam ...
