The prebiotic molecular inventory of Serpens SMM1 I. An investigation of the isomers CHNCO and HOCHCN
N. F. W. Ligterink, A. Ahmadi, A. Coutens +6
Methyl isocyanate (CHNCO) and glycolonitrile (HOCHCN) are isomers and prebiotic molecules that are involved in the formation of peptide structures and the nucleobase ad…
Deterministic loading and phase shaping of microwaves onto a single artificial atom
W. -J. Lin, Y. Lu, P. Y. Wen +12
Loading quantum information deterministically onto a quantum node is an important step towards a quantum network. Here, we demonstrate that coherent-state microwave photons, with a…
Correlating spectral and timing properties in the evolving jet of the micro blazar MAXI J1836-194
M. Lucchini, T. D. Russell, S. B. Markoff +4
During outbursts, the observational properties of black hole X-ray binaries (BHXBs) vary on timescales of days to months. These relatively short timescales make these systems ideal…
Mathematics Indicates That an HIV-Style Strategy Could Be Applied to Manage the Coronavirus
Julie Rowlett
We have learned to live with many potentially deadly viruses for which there is no vaccine, no immunity, and no cure. We do not live in constant fear of these viruses, instead, we…
Analysis and Design of Partially Information- and Partially Parity-Coupled Turbo Codes
Min Qiu, Xiaowei Wu, Alexandre Graell i Amat +1
In this paper, we study a class of spatially coupled turbo codes, namely partially information- and partially parity-coupled turbo codes. This class of codes enjoy several advantag…
Dust polarized emission observations of NGC 6334; BISTRO reveals the details of the complex but organized magnetic field structure of the high-mass star-forming hub-filament network
D. Arzoumanian, R. Furuya, T. Hasegawa +145
[Abridged] Filaments and hubs have received special attention recently thanks to studies showing their role in star formation. While the column density and velocity structures of b…
Carbon Chain Chemistry in Hot-Core Regions around Three Massive Young Stellar Objects Associated with 6.7 GHz Methanol Masers
Kotomi Taniguchi, Eric Herbst, Liton Majumdar +7
We have carried out observations of CCH (), CHCN (), and three C isotopologues of HCN () toward three massive young stellar objects (MYSOs)…
ALMA detects molecular gas in the halo of the powerful radio galaxy TXS 0828+193
Judit Fogasy, Kirsten K. Knudsen, Guillaume Drouart +1
Both theoretical and observational results suggest that high-redshift radio galaxies (HzRGs) inhabit overdense regions of the universe and might be the progenitors of local, massiv…
A low frequency study of linear polarization in radio galaxies
Vijay H. Mahatma, Martin J. Hardcastle, Jeremy Harwood +4
Radio galaxies are linearly polarized -- an important property that allows us to infer the properties of the magnetic field of the source and its environment. However at low freque…
Charge Order Lock-in by Electron-Phonon Coupling in LaEuSrCuO
Qisi Wang, K. von Arx, M. Horio +11
We report an ultrahigh resolution resonant inelastic x-ray scattering (RIXS) study of the in-plane bond-stretching phonon mode in stripe-ordered cuprate LaEuSr$_{…
Microscopic Metavehicles Powered and Steered by Embedded Optical Metasurfaces
Daniel Andrén, Denis G. Baranov, Steven Jones +3
Nanostructured dielectric metasurfaces offer unprecedented opportunities to manipulate light by imprinting an arbitrary phase-gradient on an impinging wavefront. This has resulted…
Gas-phase Elemental abundances in Molecular cloudS (GEMS) III. Unlocking the CS chemistry: the CS+O reaction
N. Bulut, O. Roncero, A. Aguado +36
CS is among the most abundant gas-phase S-bearing molecules in cold dark molecular clouds. It is easily observable with several transitions in the millimeter wavelength range, and…
Ultimate quantum limit for amplification: a single atom in front of a mirror
Emely Wiegand, Ping-Yi Wen, Per Delsing +2
We investigate three types of amplification processes for light fields coupling to an atom near the end of a one-dimensional semi-infinite waveguide. We consider two setups where a…
The CoESCA station at BESSY: Auger electron-Photoelectron coincidences from surfaces demonstrated for Ag MNN
T. Leitner, A. Born, I. Bidermane +8
In this work, we present the CoESCA station for electron-electron coincidence spectroscopy from surfaces, built in a close collaboration between Uppsala University and Helmholtz-Ze…
Microscopic understanding of ultrafast charge transfer in van-der-Waals heterostructures
R. Krause, S. Aeschlimann, M. Chavez-Cervantes +7
Van-der-Waals heterostructures show many intriguing phenomena including ultrafast charge separation following strong excitonic absorption in the visible spectral range. However, de…
Chromatic periodic activity down to 120 MHz in a Fast Radio Burst
Inés Pastor-Marazuela, Liam Connor, Joeri van Leeuwen +34
Fast radio bursts (FRBs) are extragalactic astrophysical transients whose brightness requires emitters that are highly energetic, yet compact enough to produce the short, milliseco…
Determining Context Factors for Hybrid Development Methods with Trained Models
Jil Klünder, Dzejlana Karajic, Paolo Tell +6
Selecting a suitable development method for a specific project context is one of the most challenging activities in process design. Every project is unique and, thus, many context…
Stoichiometric Bi2Se3 Topological Insulator Ultra-Thin Films Obtained Through a New Fabrication Process for Optoelectronic Applications
Matteo Salvato, Mattia Scagliotti, Maurizio De Crescenzi +7
A new fabrication process is developed for growing Bi2Se3 topological insulators in the form of nanowires/nanobelts and ultra-thin films. It consists of two consecutive procedures:…
Photodissociation Region Diagnostics Across Galactic Environments
Thomas G. Bisbas, Jonathan C. Tan, Kei E. I. Tanaka

Nelia Charalambous, Zhiqin Lu, Julie Rowlett
We demonstrate lower bounds for the eigenvalues of compact Bakry-Emery manifolds with and without boundary. The lower bounds for the first eigenvalue rely on a generalised maximum…
One can hear the corners of a drum
