  • R-band polarization curves of 48 BL Lacs

    We investigate the optical polarization properties of high-energy BL Lac objects using data from the RoboPol blazar monitoring program and the Nordic Optical Telescope. We wish...
  • A VLA survey of magnetic CVs. I. The data

    The Jansky Very Large Array was used to observe 121 magnetic cataclysmic variables (MCVs). We report radio detections of 18 stars. Thirteen are new radio sources, increasing the...
  • Optical Polarimetric Catalog for the SMC

    An optical polarimetric catalog for the Small Magelanic Cloud (SMC) is presented. It gives intrinsic and observed polarizations in the V-band for a total of 7207 stars located...
  • Polarimetry toward sightlines through ChaI

    We have obtained optical multi-band polarimetry toward sightlines through the Chamaeleon I cloud, particularly in the vicinity of the young B9/A0 star HD 97300. We show, in...
  • Polarisation at 850mu{m} in OMC-2 and OMC-3

    The SCUBA polarized 850um thermal emission data of the OMC-2 region in Orion A are added to and homogeneously reduced with data already available in the OMC-3 region. The data...
  • Photopolarimetry of Southern Coalsack stars

    We present new multicolor photopolarimetry of stars behind the Southern Coalsack. Analyzed together with multiband polarization data from the literature, probing the Chamaeleon...
  • Near-infrared polarimetry of M42

    We have conducted aperture polarimetry of ~500 stars of the Orion Nebula Cluster in M42 based on our wide-field (~8'x8') JHKs-band polarimetry. Most of the near-infrared (NIR)...
  • UBVRI polarimetric observations in NGC 6611

    An investigation on dust properties in the NW portion of NGC 6611 has been conducted polarimetrically to test the existence of abnormal extinction in that section of the open...
  • Rotating Wolf-Rayet stars in post RSG/LBV phase

    Wolf-Rayet (WR) stars with fast rotating cores are thought to be the direct progenitors of long-duration gamma-ray bursts (LGRBs). A well accepted evolutionary channel towards...
  • UBVRI polarisation in NGC 5749

    We present (UBVRI) multicolor linear polarimetric data for 31 of the brightest stars in the area of the open cluster NGC 5749 considered to study the properties of the...
  • Vilnius photometry in IC 59 and IC 63

    Optical and infrared continuum polarization from the interstellar medium is driven by radiative processes aligning the grains with the magnetic field. While a quantitative,...
  • 1 Month-long skylight polarization images dataset

    A public database composed of real-world color polarimetric images of the sky in various weather condition over a month (~ 08-2022) in La Timone, Marseille More information in...
