Extreme outflow velocities and weak UV emission lines indicate quasars shedding their dust cocoons

Guozhen Ma, Stefan J. Geier, Johan P. U. Fynbo +11

The recently discovered low-ionisation broad absorption line (LoBAL) quasar GQ 13092904 is unusual due to its very broad, highly blueshifted absorption troughs and an absence of…

On the collisional disalignment of dust grains in illuminated and shaded regions of IC 63

Archana Soam, B-G Andersson, Jose Acosta-Pulido +5

Interstellar dust grain alignment causes polarization from UV to mm wavelengths, allowing the study of the geometry and strength of the magnetic field. Over last couple of decades…

Probing Interstellar Grain Growth Through Polarimetry in the Taurus Cloud Complex

John E. Vaillancourt, B-G Andersson, Dan P. Clemens +4

The optical and near-infrared (OIR) polarization of starlight is typically understood to arise from the dichroic extinction of that light by dust grains whose axes are aligned with…

High-precision polarimetry of nearby stars (d<50 pc) Mapping the interstellar dust and magnetic field inside the Local Bubble

V. Piirola, A. Berdyugin, P. C. Frisch +6

We investigate the linear polarization produced by interstellar dust aligned by the magnetic field in the solar neighborhood (d< 50 pc). We also look for intrinsic effects from cir…

The Unique Blazar OJ 287 and its Massive Binary Black Hole Central Engine

Lankeswar Dey, Achamveedu Gopakumar, Mauri Valtonen +12

The bright blazar OJ 287 is the best-known candidate for hosting a nanohertz gravitational wave (GW) emitting supermassive binary black hole (SMBBH) in the present observable unive…

Mapping the Interstellar Magnetic Field Around the Heliosphere with Polarized Starlight

P. C. Frisch, A. B. Berdyugin, V. Piirola +20

Starlight that becomes linearly polarized by magnetically aligned dust grains provides a viable diagnostic of the interstellar magnetic field (ISMF). A survey is underway to map th…
