Radio/X-ray correlations and variability in the X-ray binary LS I +61°303
R. Sharma, M. Massi, M. Chernyakova +6
The high-mass X-ray binary LS I +61°303 exhibits variability in its radio and X-ray emissions, ranging from minute to hour time-scales. At such short time-scales, not much is known…
Low-frequency observations of the Giant Radio Galaxy NGC 6251
T. M. Cantwell, J. D. Bray, J. H. Croston +22
We present LOFAR observations at 150 MHz of the borderline FRI/FRII giant radio galaxy NGC 6251. This paper presents the most sensitive and highest-resolution images of NGC 6251 at…
Signatures from a merging galaxy cluster and its AGN population: LOFAR observations of Abell 1682
A. O. Clarke, A. M. M. Scaife, T. Shimwell +13
We present LOFAR data from 110--180~MHz of the merging galaxy cluster Abell 1682, alongside archival optical, radio and X-ray data. Our 6 arc-second resolution images at low freque…
The nature of the variable millimetre-selected AGN in the Brightest Cluster Galaxy of Abell 851
R. A. Cheale, J. E. Geach, A. C. Edge +2
We present the detection of a bright 3mm continuum source in the Brightest Cluster Galaxy (BCG) in Abell 851 (z=0.411) with the NOrthern Extended Millimeter Array (NOEMA). When thi…
iPTF 16hgs: A double-peaked Ca-rich gap transient in a metal poor, star forming dwarf galaxy
Kishalay De, Mansi M. Kasliwal, Therese Cantwell +18
Calcium rich gap transients represent an intriguing new class of faint and fast evolving supernovae that exhibit strong [Ca II] emission in their nebular phase spectra. In this pap…
Investigation of the cosmic ray population and magnetic field strength in the halo of NGC 891
D. D. Mulcahy, A. Horneffer, R. Beck +24
Low-frequency radio continuum observations of edge-on galaxies are ideal to study cosmic-ray electrons (CREs) in halos via radio synchrotron emission and to measure magnetic field…
Long-term radio and X-ray evolution of the tidal disruption event ASASSN-14li
J. S. Bright, R. P. Fender, S. E. Motta +12
We report on late time radio and X-ray observations of the tidal disruption event candidate ASASSN-14li, covering the first 1000 days of the decay phase. For the first da…
AMI-LA Observations of the SuperCLASS Super-cluster
C. J. Riseley, K. J. B. Grainge, Y. C. Perrott +21
We present a deep survey of the SuperCLASS super-cluster - a region of sky known to contain five Abell clusters at redshift - performed using the Arcminute Microkelvin I…
Up and Down the Black Hole Radio/X-ray Correlation: the 2017 mini-outbursts from Swift J1753.5-0127
R. M. Plotkin, J. Bright, J. C. A. Miller-Jones +20
The candidate black hole X-ray binary Swift J1753.5-0127 faded to quiescence in 2016 November, after a prolonged outburst that was discovered in 2005. Nearly three months later the…
AMI-CL J0300+2613: a Galactic anomalous-microwave-emission ring masquerading as a galaxy cluster
Yvette C. Perrott, Therese M. Cantwell, Steve H. Carey +17
The Arcminute Microkelvin Imager (AMI) carried out a blind survey for galaxy clusters via their Sunyaev-Zel'dovich effect decrements between 2008 and 2011. The first detection, kno…
A tale of two transients: GW170104 and GRB170105A
V. Bhalerao, M. M. Kasliwal, D. Bhattacharya +30
We present multi-wavelength follow-up campaigns by the AstroSat-CZTI and GROWTH collaborations to search for an electromagnetic counterpart to the gravitational wave event GW170104…
A Multi-telescope Campaign on FRB 121102: Implications for the FRB Population
C. J. Law, M. W. Abruzzo, C. G. Bassa +33
We present results of the coordinated observing campaign that made the first subarcsecond localization of a Fast Radio Burst, FRB 121102. During this campaign, we made the first si…
