A Large Scale, Low Frequency Murchison Widefield Array Survey of Galactic HII regions between 260\340

Hindson, L.; Johnston-Hollitt, M.; Hurley-Walker, N.; Callingham, J. R.; Su, H.; Morgan, J.; Bell, M.; Bernardi, G.; Bowman, J. D.; Briggs, F.; Cappallo, R. J.; Deshpande, A. A.; Dwarakanath, K. S.; For, B. -Q; Gaensler, B. M.; Greenhill, L. J.; Hancock, P.; Hazelton, B. J.; Kapinska, A. D.; Kaplan, D. L.; Lenc, E.; Lonsdale, C. J.; Mckinley, B.; McWhirter, S. R.; Mitchell, D. A.; Morales, M. F.; Morgan, E.; Oberoi, D.; Offringa, A.; Ord, S. M.; Procopio, P.; Prabu, T.; UdayaShankar, N.; Srivani, K. S.; Staveley-Smith, L.; Subrahmanyan, R.; Tingay, S. J.; Wayth, R. B.; Webster, R. L.; Williams, A.; Williams, C. L.; Wu, C.; Zheng, Q. (2016-05-17)

We have compiled a catalogue of HII regions detected with the Murchison Widefield Array (MWA) between 72 and 231MHz. The multiple frequency bands provided by the MWA allow us identify the characteristic spectrum generated ...

Universal sequences for the order-automorphisms of the rationals

Hyde, James; Jonusas, Julius; Mitchell, J. D.; Peresse, Y. H. (2016-05-13)

In this paper, we consider the group Aut$(\mathbb{Q}, \leq)$ of order-automorphisms of the rational numbers, proving a result analogous to a theorem of Galvin's for the symmetric group. In an announcement, Kh\'elif states ...

The Population of Compact Radio Sources in the Orion Nebula Cluster

Forbrich, Jan; Rivilla, Victor M.; Menten, Karl M.; Reid, Mark J.; Chandler, Claire J.; Rau, Urvashi; Bhatnagar, Sanjay; Wolk, Scott J.; Meingast, Stefan (2016-05-10)

We present a deep centimeter-wavelength catalog of the Orion Nebula Cluster (ONC), based on a 30h single-pointing observation with the Karl G. Jansky Very Large Array in its high-resolution A-configuration using two 1 GHz ...

Probing the Dragonfish star-forming complex: : the ionizing population of the young massive cluster Mercer 30

Fuente, D. de la; Najarro, F.; Borissova, J.; Alegría, S. Ramírez; Hanson, M. M.; Trombley, C.; Figer, D. F.; Davies, B.; Garcia, M.; Kurtev, R.; Urbaneja, M. A.; Smith, L. C.; Lucas, P. W.; Herrero, A. (2016-05-01)

The Dragonfish Nebula has been recently claimed to be powered by a superluminous but elusive OB association. Instead, systematic searches in near-infrared photometric surveys have found many other cluster candidates on ...

Utilization of the depolarization ratio derived by AERONET Sun/sky radiometer data for type confirmation of a mixed aerosol plume over East Asia

Noh, Y. M.; Shin, Sungkyun; Lee, KwonHo; Mueller, Detlef; Kim, Kwanchul (2016-04-24)

This article confirms the utilization of depolarization ratio derived by ground-based Aerosol Robotic Network (AERONET) Sun/sky radiometer data obtained during a high-PM10 episode at Gwangju, Korea (35.10° N, 126.53° E) ...

Cyclotomic Gaudin models: construction and Bethe ansatz

Vicedo, Benoit; Young, Charles A. S. (2016-04-22)

To any simple Lie algebra $\mathfrak g$ and automorphism $\sigma:\mathfrak g\to \mathfrak g$ we associate a cyclotomic Gaudin algebra. This is a large commutative subalgebra of $U(\mathfrak g)^{\otimes N}$ generated by a ...

Abundances of carbon-enhanced metal-poor stars as constraints on their formation

Hansen, C.J.; Nordström, B.; Hansen, T.T.; Kennedy, C.R.; Placco, V.M.; Beers, T.C.; Andersen, J.; Cescutti, Gabriele; Chiappini, Cristina (2016-04-01)

Context. An increasing fraction of carbon-enhanced metal-poor (CEMP) stars is found as their iron abundance, [Fe/H], decreases below [Fe/H] =−2.0. The CEMP-s stars have the highest absolute carbon abundances, [C/H], and ...

A SCUBA-2 survey of FeLoBAL QSOs : Are FeLoBALs in a `transition phase' between ULIRGs and QSOs?

Coppin, Kristen; Stevens, Jason A.; Farrah, Duncan; Geach, James; Alexander, Dave M.; Hickox, Ryan C.; Smith, Daniel; Wardlow, Julie L.; Violino, Giulio (2016-04-01)

It is thought that a class of broad absorption line (BAL) QSOs, characterised by Fe absorption features in their UV spectra (called `FeLoBALs'), could mark a transition stage between the end of an obscured starburst event ...

A method for selecting M dwarfs with an increased likelihood of unresolved ultracool companionship

Cook, Neil; Pinfield, D.J.; Marocco, F.; Burningham, B.; Jones, H.R.A.; Frith, James; Zhong, J.; Luo, A.; Qi, Z.; Lucas, P.W.; Gromadzki, Mariusz; Day-Jones, Avril; Kurtev, Radostin; Guo, Y.; Wang, Y.; Bai, Y.; Yi, Z.; Smart, R. (2016-04-01)

Locating ultracool companions to M dwarfs is important for constraining low-mass formation models, the measurement of substellar dynamical masses and radii, and for testing ultracool evolutionary models. We present an ...

Galaxy And Mass Assembly (GAMA) : The 325-MHz Radio Luminosity Function of AGN and Star Forming Galaxies

Prescott, Matthew; Mauch, T.; Jarvis, M.J.; McAlpine, K.; Smith, Daniel; Fine, S.; Johnston, R.; Hardcastle, M.J.; Baldry, I. K.; Brough, S.; Brown, M. J. I.; Bremer, M.N.; Driver, S. P.; Hopkins, A. M.; Kelvin, L. S.; Loveday, J.; Norberg, P.; Obreschkow, D.; Sadler, E.M. (2016-03-21)

Measurement of the evolution of both active galactic nuclei (AGN) and star-formation in galaxies underpins our understanding of galaxy evolution over cosmic time. Radio continuum observations can provide key information ...
