Violent quenching : Molecular Gas Blown to 1000 km s -1 during a Major Merger

Geach, J. E.; Tremonti, C.; Diamond-Stanic, A. M.; Sell, P. H.; Kepley, A. A.; Coil, A. L.; Rudnick, G.; Hickox, R. C.; Moustakas, J.; Yang, Yujin (2018-08-23)

We present Atacama Large Millimeter/submillimeter Array observations of a massive () compact ( pc) merger remnant at z = 0.66 that is driving a 1000 km s -1 outflow of cool gas, with no observational trace of an active ...

Detection of non-thermal X-ray emission in the lobes and jets of Cygnus A

Vries, M. N. de; Wise, M. W.; Huppenkothen, D.; Nulsen, P. E. J.; Snios, B.; Hardcastle, M. J.; Birkinshaw, M.; Worrall, D. M.; Duffy, R. T.; McNamara, B. R. (2018-08-21)

We present a spectral analysis of the lobes and X-ray jets of Cygnus A, using more than 2 Ms of $\textit{Chandra}$ observations. The X-ray jets are misaligned with the radio jets and significantly wider. We detect non-thermal ...

The origin of radio emission in broad absorption line quasars: Results from the LOFAR Two-metre Sky Survey

Morabito, L. K.; Matthews, J. H.; Best, P. N.; Gürkan, G.; Jarvis, M. J.; Prandoni, I.; Duncan, K. J.; Hardcastle, M. J.; Kunert-Bajraszewska, M.; Mechev, A. P.; Mooney, S.; Sabater, J.; Röttgering, H. J. A.; Shimwell, T. W.; Smith, D. J. B.; Tasse, C.; Williams, W. L. (2018-08-16)

We present a study of the low-frequency radio properties of broad absorption line quasars (BALQSOs) from the LOFAR Two-metre Sky-Survey Data Release 1 (LDR1). The value-added LDR1 catalogue contains Pan-STARRS counterparts, ...

Resolving the ISM at the peak of cosmic star formation with ALMA - The distribution of CO and dust continuum in z~2.5 sub-millimetre galaxies

Rivera, Gabriela Calistro; Hodge, J. A.; Smail, Ian; Swinbank, A. M.; Weiß, A.; Wardlow, J. L.; Walter, F.; Rybak, M.; Chen, Chian-Chou; Brandt, W. N.; Coppin, K.; Cunha, E. da; Dannerbauer, H.; Greve, T. R.; Karim, A.; Knudsen, K. K.; Schinnerer, E.; Venemans, B.; Werf, P. P. van der (2018-08-09)

We use ALMA observations of four sub-millimetre galaxies (SMGs) at $z\sim2-3$ to investigate the spatially resolved properties of the inter-stellar medium (ISM) at scales of 1--5 kpc (0.1--0.6$''$). The velocity fields of ...

A new near-IR window of low extinction in the Galactic plane

Minniti, Dante; Saito, Roberto K.; Gonzalez, Oscar A.; Alonso-García, Javier; Rejkuba, Marina; Barbá, Rodolfo; Irwin, Mike; Kammers, Roberto; Lucas, Philip; Majaess, Daniel; Valenti, Elena (2018-08-01)

Aims. The windows of low extinction in the Milky Way (MW) plane are rare but important because they enable us to place structural constraints on the opposite side of the Galaxy, which has hither to been done rarely. Methods. ...

Concurrent formation of supermassive stars and globular clusters : implications for early self-enrichment

Gieles, Mark; Charbonnel, Corinne; Krause, Martin; Henault-Brunet, Vincent; Agertz, Oscar; Lamers, Henny; Bastian, Nathan; Gualandris, Alessia; Zocchi, Alice; Petts, James (2018-08-01)

We present a model for the concurrent formation of globular clusters (GCs) and supermassive stars (SMSs, ≳10 3M ⊙) to address the origin of the HeCNONaMgAl abundance anomalies in GCs. GCs form in converging gas flows and ...

Main sequence of star forming galaxies beyond the Herschel confusion limit

Pearson, W. J.; Wang, L.; Hurley, P. D.; Małek, K.; Buat, V.; Burgarella, D.; Farrah, D.; Oliver, S. J.; Smith, D. J. B.; Tak, F. F. S. van der (2018-07-30)

Context. Deep far-infrared (FIR) cosmological surveys are known to be affected by source confusion, causing issues when examining the main sequence (MS) of star forming galaxies. In the past this has typically been partially ...

Investigating the cause of the $α\,$-$\,z$ relation

Morabito, Leah K.; Harwood, Jeremy J. (2018-07-27)

The correlation between radio spectral index and redshift has long been used to identify high redshift radio galaxies, but its cause is unknown. Traditional explanations invoke either $(i)$ intrinsic relations between ...

A machine-learning method for identifying multi-wavelength counterparts of submillimeter galaxies : training and testing using AS2UDS and ALESS

An, FangXia; Stach, S. M.; Smail, Ian; Swinbank, A. M.; Almaini, O.; Hartley, W.; Maltby, D. T.; Ivison, R. J.; Arumugam, V.; Wardlow, J. L.; Cooke, E. A.; Gullberg, B.; Chen, Chian-Chou; Geach, J. E.; Scott, D.; Dunlop, J. S.; Farrah, D.; Werf, P. van der; Blain, A. W.; Conselice, C.; Michałowski, M. J.; Chapman, S. C.; Coppin, K. E. K. (2018-07-27)

We describe the application of supervised machine-learning algorithms to identify the likely multiwavelength counterparts to submillimeter sources detected in panoramic, single-dish submillimeter surveys. As a training ...

Evolution of N/O ratios in galaxies from cosmological hydrodynamical simulations

Vincenzo, Fiorenzo; Kobayashi, Chiaki (2018-07-21)

We study the redshift evolution of the gas-phase O/H and N/O abundances, both (i) for individual interstellar medium (ISM) regions within single spatially resolved galaxies and (ii) when dealing with average abundances in ...
