- The SEDs and host galaxies of the dustiest GRB afterglows (2011, background): “Measurements for different Galactic sight-lines (e.g., Predehl & Schmitt 1995; Güver & Özel 2009) show an almost universal value of around NH/AV ≈ 2 × 1021 cm−2/mag, while the matter probed by afterglows can yield metal-to-dust ratios up to and sometimes even above 100-times higher (e.g., Watson et…”
- A Deep Chandra X-Ray Study of Neutron Star Coalescence GW170817 (2017, methodology): “The absorption column in all cases was fixed to NH= 7.5×1020 cm−2, derived by converting the Galactic optical extinction AV = 0.338 (Schlafly & Finkbeiner 2011) to a hydrogen column density via the relation NH(cm−2) ≈ 2.21× 1021AV (Güver & Özel 2009).”
- Trumpeting M dwarfs with CONCH-SHELL: a catalogue of nearby cool host-stars for habitable exoplanets and life (2014, methodology): “We adopted NH = 2.21 × 10 21cm−2AV (Güver & Özel 2009), characteristic of the diffuse ISM.”
- THE DISTANCE, MASS, AND RADIUS OF THE NEUTRON STAR IN 4U 1608−52 (2008, methodology): “The observed relation between hydrogen column density and optical extinction has been the subject of numerous studies (e.g., Görenstein 1975; Predehl & Schmitt 1996; Güver & Özel 2009).”
- THE MASS AND RADIUS OF THE NEUTRON STAR IN 4U 1820−30 (2010, result): “We note that converting the reddening, E(B−V ) = 0.32±0.03, measured by Heasley et al. (2000) using the conversion NH = (6.86 ± 0.27) × 10 21 × E(B − V ) (Güver & Özel 2009) yields an equivalent hydrogen column density of (2.20 ± 0.22) × 1021 cm−2, which is in agreement with the value given above.”
- THE DENSE MATTER EQUATION OF STATE FROM NEUTRON STAR RADIUS AND MASS MEASUREMENTS (2015, methodology): “Foight et al. (2015) analysed the archival Chandra observations of all the supernova remnants used in the Güver & Özel (2009) study to improve the relation between the optical extinction AV and the hydrogen column density NH. Performing a uniform analysis of the data set and taking into account…”
- KILOPARSEC-SCALE DUST DISKS IN HIGH-REDSHIFT LUMINOUS SUBMILLIMETER GALAXIES (2016, methodology): “The corresponding extinction (Av) values were calculated as in Güver & Özel (2009).”
- A CHANDRA PERSPECTIVE ON GALAXY-WIDE X-RAY BINARY EMISSION AND ITS CORRELATION WITH STAR FORMATION RATE AND STELLAR MASS: NEW RESULTS FROM LUMINOUS INFRARED GALAXIES (2010, methodology): “To estimate the effect that obscuration can have on the observed 2–10 keV power for ULIRG levels of extinction, we first convertedAV to NH following the relation NH ≈ 2.3×1021AV cm−2 from Güver & Özel (2009), which was calibrated using measurements of various columns through the Milky Way.”
