• #### ALMA Detection of Extended [C II] Emission in Himiko at z = 6.6 ﻿

(IoP, 2018-02-10)
Himiko is one of the most luminous Ly{\alpha} emitters at z = 6.595. It has three star forming clumps detected in the rest-frame UV, with a total SFR = 20 M$_\odot$/yr. We report the ALMA detection of the [CII]158$\mu$m ...
• #### ALMA Long Baseline Campaigns: Phase Characteristics of Atmosphere at Long Baselines in the Millimeter and Submillimeter Wavelengths ﻿

(IOP Publishing, 2017-02-06)
We present millimeter- and submillimeter-wave phase characteristics measured between 2012 and 2014 of Atacama Large Millimeter/submillimeter Array long baseline campaigns. This paper presents the first detailed investigation ...
• #### ALMA long baseline phase calibration using phase referencing ﻿

(SPIE, 2016-08-08)
© 2016 SPIE.The Atacama Large Millimeter/submillimeter Array (ALMA) is the world's largest millimeter/submillimeter telescope and provides unprecedented sensitivities and spatial resolutions. To achieve the highest imaging ...
• #### ALMA observations of cold molecular gas in AGN hosts at z ~ 1.5 – evidence of AGN feedback? ﻿

(Oxford University Press, 2017-07)
Similarly to the cosmic star formation history, the black hole accretion rate density of the Universe peaked at 1<$z$<3. This cosmic epoch is hence best suited for investigating the effects of radiative feedback from active ...
• #### Alma Observations of Massive Molecular Gas Filaments Encasing Radio Bubbles in the Phoenix Cluster ﻿

(Institute of Physics, 2017-02-14)
We report new ALMA observations of the CO(3-2) line emission from the 2.1 $\pm$ 0.3 x 10$^{10}$ $\textit{M}$$\odot$ molecular gas reservoir in the central galaxy of the Phoenix cluster. The cold molecular gas is fueling a ...
• #### ALMA Observations of the Debris Disk of Solar Analogue τ Ceti ﻿

(American Astronomical Society, 2016-09-10)
We present 1.3 mm observations of the Sun-like star τ Ceti with the Atacama Large Millimeter/submillimeter Array that probe angular scales of (4 au). This first interferometric image of the τ Ceti system, which hosts both ...
• #### ALMA observations of the multiplanet system 61 Vir: What lies outside super-Earth systems? ﻿

(Oxford University Press, 2017-05-06)
A decade of surveys has hinted at a possible higher occurrence rate of debris discs in systems hosting low mass planets. This could be due to common favourable forming conditions for rocky planets close in and planetesimals ...
• #### ALMA observations of the η Corvi debris disc: Inward scattering of CO-rich exocomets by a chain of 3-30 M⊕ planets? ﻿

(Oxford University Press, 2017-01-01)
While most of the known debris discs present cold dust at tens of astronomical unit (au), a few young systems exhibit hot dust analogous to the Zodiacal dust. η Corvi is particularly interesting as it is old and it has ...
• #### ALMA Observations Show Major Mergers Among the Host Galaxies of Fast-growing, High-redshift, Supermassive Black Holes ﻿

(IOP Publishing, 2017-02-10)
We present new ALMA band-7 data for a sample of six luminous quasars at $z$ $\simeq$ 4.8, powered by fast-growing supermassive black holes (SMBHs) with rather uniform properties: the typical accretion rates and black hole ...
• #### ALMA suggests outflows in z ~ 5.5 galaxies ﻿

(Oxford University Press, 2018-01-01)
We present the first attempt to detect outflows from galaxies approaching the Epoch of Reionization (EoR) using a sample of 9 star-forming ($\rm SFR=31\pm 20~M_{\odot}~yr^{-1}$) $z\sim 5.5$ galaxies for which the [CII]158$\mu$m ...
• #### ALMA Survey of Lupus Protoplanetary Disks II: Gas Disk Radii ﻿

We present ALMA Band 6 observations of a complete sample of protoplanetary disks in the young (1-3 Myr) Lupus star-forming region, covering the 1.33 mm continuum and the 12CO, 13CO, and C18O J=2-1 lines. The spatial ...
• #### ALMA SURVEY of LUPUS PROTOPLANETARY DISKS. I. DUST and GAS MASSES ﻿

• #### Almendrals, Valparaiso ﻿

(2007-06-14)
A large coastal settlement in its landscape, with a view of the Beagle; with colouring instructions.
• #### Almost global consensus on the $\textit{n}$-sphere ﻿

This paper establishes novel results regarding the global convergence properties of a large class of consensus protocols for multi-agent systems that evolve in continuous time on the n-dimensional unit sphere or n-sphere. ...

• #### AlN/CrN multilayer structures with increased thermal stability ﻿

(Elsevier, 2017-03-15)
CrAlYN nanolayered coatings of greatly enhanced thermal stability have been developed by doping with levels of Y up to 9 at.%. This prevented the complete dissolution of the layered structure after annealing at 1100 °C in ...
• #### Alone versus In-a-group: A Comparative Analysis of Facial Affect Recognition ﻿

(Association for Computing Machinery, 2016-10-19)
Automatic affect analysis and understanding has become a well established research area in the last two decades. Recent works have started moving from individual to group scenarios. However, little attention has been paid ...

(Nicola Zanichelli, 2017-10-29)
Let G be a finite solvable or symmetric group and let B be a 2-block of G. We construct a canonical correspondence between the irreducible characters of height zero in B and those in its Brauer first main correspondent. ...
