        The nature of the variable millimetre-selected AGN in the Brightest Cluster Galaxy of Abell 851 

        Cheale, R. A.; Geach, J. E.; Edge, A. C.; Perrott, Y. C.; Cantwell, T. (2018-11-21)
        We present the detection of a bright 3mm continuum source in the brightest cluster galaxy (BCG) in Abell 0851 (z = 0.411) with the NOrthern Extended Millimeter Array (NOEMA). When this detection is compared to other ...

        LoTSS DR1 : Double-double radio galaxies in the HETDEX field 

        Mahatma, V. H.; Hardcastle, M. J.; Williams, W. L.; Best, P. N.; Croston, J. H.; Duncan, K.; Mingo, B.; Morganti, R.; Brienza, M.; Cochrane, R. K.; Gürkan, G.; Harwood, J. J.; Jarvis, M. J.; Jamrozy, M.; Jurlin, N.; Morabito, Leah K.; Röttgering, H. J. A.; Sabater, J.; Shimwell, T. W.; Smith, D. J. B.; Shulevski, A.; Tasse, C. (2018-11-20)
        Double-double radio galaxies (DDRGs) represent a short but unique phase in the life-cycle of some of the most powerful radio-loud active galactic nuclei (RLAGN). These galaxies display large-scale remnant radio plasma in ...

        LoTSS/HETDEX: Disentangling star formation and AGN activity in gravitationally-lensed radio-quiet quasars 

        Stacey, H. R.; McKean, J. P.; Jackson, N. J.; Best, P. N.; Rivera, G. Calistro; Callingham, J. R.; Duncan, K. J.; Gürkan, G.; Hardcastle, M. J.; Iacobelli, M.; Mechev, A. P.; Morabito, L. K.; Prandoni, I.; Röttgering, H. J. A.; Sabater, J.; Shimwell, T. W.; Tasse, C.; Williams, W. L. (2018-11-19)
        Determining the star-forming properties of radio-quiet quasars is important for understanding the co-evolution of star formation and black hole accretion. Here, we present the detection of the gravitationally-lensed ...

        Blazars in the LOFAR Two-Metre Sky Survey First Data Release 

        Mooney, S.; Quinn, J.; Callingham, J. R.; Morganti, R.; Duncan, K.; Morabito, Leah K.; Best, P. N.; Gürkan, G.; Hardcastle, M. J.; Prandoni, I.; Röttgering, H. J. A.; Sabater, J.; Shimwell, T. W.; Shulevski, A.; Tasse, C.; Williams, W. L. (2018-11-19)
        Historically, the blazar population has been poorly understood at low frequencies because survey sensitivity and angular resolution limitations have made it difficult to identify megahertz counterparts. We used the LOFAR ...

        The LOFAR Two-metre Sky Survey IV. First Data Release: Photometric redshifts and rest-frame magnitudes 

        Duncan, Kenneth J; Sabater, J.; Röttgering, H. J. A.; Jarvis, M. J.; Smith, D. J. B.; Best, P. N.; Callingham, J. R.; Cochrane, R.; Croston, J. H.; Hardcastle, M. J.; Mingo, B.; Morabito, L.; Nisbet, D.; Prandoni, I.; Shimwell, T. W.; Tasse, C.; White, G. J.; Williams, W. L.; Alegre, L.; Chyży, K. T.; Gürkan, G.; Hoeft, M.; Kondapally, R.; Mechev, A. P.; Miley, G. K.; Schwarz, D. J.; Weeren, R. J. van (2018-11-19)
        The LOFAR Two-metre Sky Survey (LoTSS) is a sensitive, high-resolution 120-168 MHz survey of the Northern sky. The LoTSS First Data Release (DR1) presents 424 square degrees of radio continuum observations over the HETDEX ...

        LOFAR observations of the XMM-LSS field 

        Hale, C. L.; Williams, W.; Jarvis, M. J.; Hardcastle, M. J.; Morabito, Leah K.; Shimwell, T. W.; Tasse, C.; Best, P. N.; Harwood, J. J.; Heywood, I.; Prandoni, I.; Röttgering, H. J. A.; Sabater, J.; Smith, D. J. B.; Weeren, R. J. van (2018-11-19)
        We present observations of the XMM Large-Scale Structure (XMM-LSS) field observed with the LOw Frequency ARray (LOFAR) at 120-168 MHz. Centred at a J2000 declination of $-4.5^{\circ}$, this is a challenging field to observe ...

        Radio-loud AGN in the first LoTSS data release: The lifetimes and environmental impact of jet-driven sources 

        Hardcastle, M. J.; Williams, W. L.; Best, P. N.; Croston, J. H.; Duncan, K. J.; Rottgering, H. J. A.; Sabater, J.; Shimwell, T. W.; Tasse, C.; Callingham, J. R.; Cochrane, R. K.; Gasperin, F. de; Gurkan, G.; Jarvis, M. J.; Mahatma, V.; Miley, G. K.; Mingo, B.; Mooney, S.; Morabito, L. K.; O'Sullivan, S. P.; Prandoni, I.; Shulevski, A.; Smith, D. J. B. (2018-11-19)
        We constructed a sample of 23,344 radio-loud active galactic nuclei (RLAGN) from the catalogue derived from the LOFAR Two-Metre Sky Survey (LoTSS) survey of the HETDEX Spring field. Although separating AGN from star-forming ...

        A candidate super-Earth planet orbiting near the snow line of Barnard's star

S.; Caballero, J. A.; Hatzes, A.; Herrero, E.; Jeffers, S. V.; Lafarga, M.; Murgas, F.; Rodríguez, E.; Strachan, J. B. P.; Tal-Or, L.; Teske, J.; Toledo-Padrón, B.; Zechmeister, M.; Quirrenbach, A.; Amado, P. J.; Azzaro, M.; Béjar, V. J. S.; Barnes, J. R.; Berdiñas, Z.

(2018-11-15)
        Barnard’s star is a red dwarf, and has the largest proper motion (apparent motion across the sky) of all known stars. At a distance of 1.8 parsecs, it is the closest single star to the Sun; only the three stars in the α ...

        The LoTSS view of radio AGN in the local Universe. The most massive galaxies are always switched on 

        Sabater, J.; Best, P.N.; Hardcastle, M. J.; Shimwell, T. W.; Tasse, C.; Williams, W. L.; Brüggen, M.; Cochrane, R. K.; Croston, J. H.; Gasperin, F. de; Duncan, K. J.; Gürkan, G.; Mechev, A.

        This paper presents a study of the local radio source population, by cross-comparing the data from the first data release (DR1) of the LOFAR Two-Metre Sky Survey (LoTSS) with the Sloan Digital Sky Survey (SDSS) DR7 main ...

        3D shape of Orion A from Gaia DR2 

        Grossschedl, Josefa E.; Alves, Joao; Meingast, Stefan; Ackerl, Christine; Ascenso, Joana; Bouy, Herve; Burkert, Andreas; Forbrich, Jan; Fuernkranz, Verena; Goodman, Alyssa; Hacar, Alvaro; Herbst-Kiss, Gabor; Lada, Charles J.; Larreina, Irati; Leschinski, Kieran; Lombardi, Marco; Moitinho, Andre; Mortimer, Daniel; Zari, Eleonora (2018-11-14)
        We use the Gaia DR2 distances of about 700 mid-infrared selected young stellar objects in the benchmark giant molecular cloud Orion A to infer its 3D shape and orientation. We find that Orion A is not the fairly straight ...
