Image quality of wide field observations with the ALMA has been studied with imaging simulations. Results of the simulations showed that antenna pointing errors are a serious problem for obtaining high quality images because they make a large error in visibilities in the central (u,v) hole estimated by mosaicing data processings. The ALMA Compact Array (ACA) with more than 10 smaller dishes (6-...
This memo presents the case for adding smaller antennas to the ALMA array. Smaller, higher precision antennas are better able to exploit the excellent submillimeter potential of the 5000 m altitude site, and are better matched to the angular size of many submillimeter sources. Model studies show that the image delity of mosaiced observations with the ALMA array will be limited by pointing and s...
Context. We have performed a spectral line survey called EMoCA toward Sagittarius B2(N) between 84.0 and 114.4 GHz with the Atacama Large Millimeter/submillimeter Array (ALMA) in its Cycles 0 and 1. Line intensities of the main isotopic species of ethyl cyanide and its singly 13C-substituted isotopomers observed toward the hot molecular core Sagittarius B2(N2) suggest that the doubly 13C-substi...
The ALMA front-end cryostat is a cylinder 1-m in diameter and 0.5-m high which holds up to 10 receivers operating in different frequency bands for full details see [1]. Figure 1 shows the cryostat in a preliminary mounting frame which allows initial RF measurements to be made using the adjacent electronics and control racks. Figure 2 shows a close-up picture of the top of the cryostat with the ...
We present new Atacama Large Millimeter/Submillimeter Array (ALMA) 850μm continuum observations of the original Lymanα Blob (LAB) in the SSA22 field at z = 3.1 (SSA22-LAB01). The ALMA map resolves the previously identified submillimeter source into three components with total flux density S850 = 1.68± 0.06 mJy, corresponding to a star formation rate of ∼150 M yr−1. The submillimeter sources are...
Background The combination treatment of golimumab (GOL), a tumor necrosis factor-alpha (TNFα) antagonist, and guselkumab (GUS), an interleukin (IL)-23 inhibitor was shown to induce higher rates clinical remission, endoscopic improvement, histologic remission than each monotherapy in randomized phase 2 induction study TNFα-naïve patients with moderate-to-severely active ulcerative colitis (UC) (...
Context. The detection of the rotational lines of CO in proto-galaxies in the early Universe provides one of the most promising ways of probing the fundamental physical properties of a galaxy, such as its size, dynamical mass, gas density, and temperature. While such observations are currently limited to the most luminous galaxies, the advent of ALMA will change the situation dramatically, resu...
CD9, a widely expressed membrane protein of the tetraspanin family, has been implicated in diverse functions, such as signal transduction, cell adhesion, and cell motility. We tested the effects of an anti-CD9 monoclonal antibody (ALMA.1) on the migration and proliferation of human vascular endothelial cells (ECs) during repair of an in vitro mechanical wound mimicking angiogenic processes. ALM...
The ALMA Common Software (ACS) is a set of application frameworks built on top of CORBA. It provides a common software infrastructure to all partners in the ALMA collaboration. The usage of ACS extends from high-level applications such as the Observation Preparation Tool [7] that will run on the desk of astronomers, down to the Control Software [6] domain. The purpose of ACS is twofold: from a ...
