Self-interacting dark matter from radiative bound-state-formation feedback
Marcos M. Flores, Kalliopi Petraki, Thomas Pignard
Observations of galactic structure motivate sizable dark-matter self-interactions at low velocities, naturally realized through light force mediators. Such mediators can also make…
SIMPLIFI -- Study of Interstellar Magnetic Polarization: a Legacy Investigation of Filaments. I. Magnetically-Guided Accretion onto the DR21 Ridge
Thushara G. S. Pillai, Jens Kauffmann, Juan D. Soler +15
We present first results from SIMPLIFI (Study of Interstellar Magnetic Polarization: a Legacy Investigation of Filaments), a SOFIA/HAWC+ polarimetric survey of Galact…
When Magnetic Fields Sculpt the Sky: The Riegel-Crutcher cloud in optical polarization
Gabriel A. P. Franco, Mayara Gomides, Zhi-Yun Li +2
Filamentary structures are ubiquitous in the interstellar medium, yet the extent to which magnetic fields influence the morphology of cold atomic gas remains an open question. The…
The Snake Filament: A study of polarization and kinematics
Farideh S. Tabatabaei, Elena Redaelli, Gabriel A. P. Franco +2
The role of magnetic fields in the formation of dense filamentary structures in molecular clouds is critical for understanding the star formation process. The Snake filament in or…
Unveiling the role of magnetic fields in an accreting filament onto a young protocluster
Farideh S. Tabatabaei, Elena Redaelli, Daniele Galli +4
In order to develop a more comprehensive picture of star formation, it is essential to understand the physical relationship between dense cores and the filaments embedding them. Th…
Magnetized filamentary gas flows feeding the young embedded cluster in Serpens South
Thushara G. S. Pillai, Dan P. Clemens, Stefan Reissl +11
Observations indicate that molecular clouds are strongly magnetized, and that magnetic fields influence the formation of stars. A key observation supporting the conclusion that mol…
Gas flow and accretion via spiral streamers and circumstellar disks in a young binary protostar
Felipe O. Alves, Paola Caselli, Josep M. Girart +4
The majority of stars are part of gravitationally bound stellar systems, such as binaries. Observations of protobinary systems constrain the conditions that lead to stellar multipl…
Magnetic field in a young circumbinary disk
Felipe O. Alves, Josep M. Girart, Marco Padovani +6
We use polarization observations of a circumbinary disk to investigate how the polarization properties change at distinct frequency bands. Our goal is to discern the main mechanism…
Probing the Structure of the Accretion Region in a Sample of Magnetic Herbig Ae/Be Stars
M. A. Pogodin, J. A. Cahuasqui, N. A. Drake +10
We present the results of a study of the temporal behaviour of several diagnostic lines formed in the region of the accretion-disk/star interaction in the three magnetic Herbig Ae…
Unveiling a network of parallel filaments in the Infrared Dark Cloud G14.225-0.506
Gemma Busquet, Qizhou Zhang, Aina Palau +10
We present the results of combined NH3(1,1) and (2,2) line emission observed with the Very Large Array and the Effelsberg 100m telescope of the Infrared Dark Cloud G14.225-0.506. T…
Interstellar reddening towards six small areas in Puppis-Vela
G. A. P. Franco
We investigate the distribution of the interstellar dust towards six small volumes of the sky in the region of the Gum nebula. New high-quality four-colour uvby and Hβ Strömgren ph…
SPARC4: A Simultaneous Polarimeter and Rapid Camera in 4 Bands
C. V. Rodrigues, F. J. Jablonski, K. Taylor +13
We present the basic concept of a new astronomical instrument: SPARC4 - Simultaneous Polarimeter and Rapid Camera in 4 bands. SPARC4 combines in one instrument: (i) photometric and…
Particle Acceleration and Magnetic Field Structure in PKS 2155-304: Optical Polarimetric Observations
U. Barres de Almeida, M. J. Ward, T. P. Dominici +5
In this paper we present multiband optical polarimetric observations of the VHE blazar PKS 2155-304 made simultaneously with a H.E.S.S./Fermi high-energy campaign in 2008, when the…
