Detecting correlated errors in twin-field quantum key distribution
B. Panchumarthi, A. Stephens, M. Beck
We experimentally demonstrate that we can detect correlated errors in a twin-field quantum key distribution (TFQKD) system by using a technique that is related to self-consistent t…
Supernovae and radio transients in M 82
S. Mattila, M. Fraser, S. J. Smartt +4
We present optical and near-infrared (IR) photometry and near-IR spectroscopy of SN 2004am, the only optically detected supernova (SN) in M 82. These demonstrate that SN 2004am was…
Red and dead: The progenitor of SN 2012aw in M95
M. Fraser, J. R. Maund, S. J. Smartt +17
Core-collapse supernovae (SNe) are the spectacular finale to massive stellar evolution. In this Letter, we identify a progenitor for the nearby core-collapse SN 2012aw in both grou…
A Photometric Redshift of z ~ 9.4 for GRB 090429B
A. Cucchiara, A. J. Levan, D. B. Fox +33
Gamma-ray bursts (GRBs) serve as powerful probes of the early Universe, with their luminous afterglows revealing the locations and physical properties of star forming galaxies at t…
The JASMIN super-data-cluster
B. N. Lawrence, V. Bennett, J. Churchill +5
The JASMIN super-data-cluster is being deployed to support the data analysis requirements of the UK and European climate and earth system modelling community. Physical colocation o…
Self-consistent state and measurement tomography with fewer measurements
A. Stephens, J. M. Cutshall, T. McPhee +1
We describe a technique for self consistently characterizing both the quantum state of a single qubit system, and the positive-operator-valued measure (POVM) that describes measure…
Constraining GRB Emission Physics with Extensive Early-Time, Multiband Follow-up
A. Cucchiara, S. B. Cenko, J. S. Bloom +21
Understanding the origin and diversity of emission processes responsible for Gamma-ray Bursts (GRBs) remains a pressing challenge. While prompt and contemporaneous panchromatic obs…
A Panchromatic JWST Spectrum of a Giant Starspot on the Fully Convective M-dwarf TOI-3884
C. A. Murray, L. Garcia, B. V. Rackham +18
TOI-3884 b is a rare super-Neptune transiting a fully convective M dwarf that hosts a persistent giant polar spot. Because the planet occults this active region during every transi…
SN 2009md: Another faint supernova from a low mass progenitor
M. Fraser, M. Ergon, J. J. Eldridge +21
We present adaptive optics imaging of the core collapse supernova (SN) 2009md, which we use together with archival \emph{Hubble Space Telescope} data to identify a coincident proge…
