  • The Wilson-Bappu effect for Mg II k-line emission widths 
    Parthasarathy, M (D.Reidel Publishing, 1985)
    The existence of a tight linear correlation between the stellar absolute magnitude Mv and the Mg II k-line emission width log WMg II k (km s/sup-1) is confirmed using IUE high-resolution (0.2 Å) data for 100 late-type stars.
  • Wind speed measurement from Shack Hartmann Wavefront Sensor data: An experimental review of cross-correlation peak detection 
    Roopashree, M. B; Vyas, A; Prasad, B. R (ACEEE, USA, 2011)
    The mean velocity of the atmospheric wind is an important parameter in characterizing the turbulence above an astronomical telescope. Real-time wind velocity measurement is exceedingly essential to update the design metrics ...
  • The WIRCAM Deep Infrared Cluster Survey I. Groups and clusters at z  ≳  1.1 
    Bielby, R. M; Finoguenov, A; Tanaka, M; McCracken, H. J; Daddi, E; Hudelot, P; Ilbert, O; Kneib, J. P; Le Fèvr, O; Mellier, Y; Nandra, K; Petitjean, P; Srianand, R; Stalin, C. S; Willott, C. J (EDP Sciences, 2010-12)
    We use a combination of CFHTLS deep optical data, WIRcam Deep Survey (WIRDS) near-infrared data and XMM-Newton survey data to identify z ≳ 1.1 clusters in the CFHTLS D1 and D4 fields. Counterparts to such clusters can not ...
  • WISE view of narrow-line Seyfert 1 galaxies: mid-infrared colour and variability

    We present the colour and flux variability analysis at 3.4 μm (W1 band) and 4.6 μm (W2 band) of 492 narrow-line Seyfert 1 (NLSy1) galaxies using archival data from the Wide-field Infrared Survey Explorer (WISE). In the ...
  • Witnessing the star formation quenching in L* ellipticals 
    Dhiwar, Suraj; Saha, Kanak; Dekel, Avishai; Paswan, Abhishek; Pandey, Divya; Cortesi, Arianna; Pandge, Mahadev (Oxford University Press on behalf of Royal Astronomical Society, 2023-02)
    We study the evolution of L∗ elliptical galaxies in the colour–magnitude diagram in terms of their star formation history and environment, in an attempt to learn about their quenching process. We have visually extracted ...
  • WKB Analysis of Axisymmetric Magneto-Rotational Instability in a Thin Accretion Disk 
    Furukawa, M; Krishan, V; Hirota, M; Yoshida, Z (The Japan Society of Plasma Science and Nuclear Fusion Research, 2006)
    The temporal behavior of axisymmetric magneto-rotational instability in a thin accretion disk is analyzed via the Wentzel-Kramars-Brillouin (WKB) method. The height of the thin disk is used as a small parameter. It is found ...

    This is a summary of the papers presented in session W1 on the papers submitted to the workshop I on the classical aspects of black holes and compact objects were classified into three categories: (i) theoretical aspects; ...
  • Workshop I: gender studies 
    Hennessey, E; Kurup, A; Meza-Montes, L; Shastri, P; Ghose, S (AIP Publishing, 2015-05)
    Participants in the Gender Studies workshop of the 5th IUPAP International Conference on Women in Physics discussed the gender question in science practice from a policy perspective, informed by investigations ...
  • Workshop report: Intersecting identities gender and intersectionality in physics 
    Hennessey, Eden; Cole, Joanne; Shastri, P; Esquivel, Jessica; Singh, Chandralekha; Johnson, Rosie; Ghose, Shohini (AIP Publishing, 2019-06)
    The concept of intersectionality refers to how our various social identities (e.g., gender, race, class) overlap to create power, privilege, or marginalization. We report on a workshop held at the International Conference ...
