We present the various science cases for building Band 1 receivers as part of ALMA's ongoing Development Program. We describe the new frequency range for Band 1 of 35-52 GHz, a range chosen to maximize the receiver suite's scientific impact. We first describe two key science drivers: 1) the evolution of grains in protoplanetary disks and debris disks, and 2) molecular gas in galaxies during the era of re-ionization. Studies of these topics with Band 1 receivers will significantly expand ALMA's… 
Dust observations with the new ALMA Band 1 receiver
The ALMA Band 1 project will expand the Atacama Large Millimeter/submillimeter Array (ALMA) access to frequencies between 35 and 52 GHz for high angular resolution and sensitivity observations from
Enabling the next generation of cm-wavelength studies of high-redshift molecular gas with the SKA
The Square Kilometre Array will be a revolutionary instrument for the study of gas in the distant Universe. SKA1 will have sufficient sensitivity to detect and image atomic 21 cm HI in individual
On the Effects of Self-obscuration in the (Sub)Millimeter Spectral Indices and the Appearance of Protostellar Disks
In this paper we explore the effects of self-obscuration in protostellar disks with a radially decreasing temperature gradient and a colder midplane. We are motivated by recent reports of resolved
Cosmology in front of the background: studying the growth of structure at CMB wavelengths
Canada has thriving communities in CMB (cosmic microwave background) studies, cosmology and submillimetre (submm) astronomy, with involvement in many facilities that featured prominently in previous
Strategies on solar observation of Atacama Large Millimeter/submillimeter Array (ALMA) band-1 receiver
ALMA covering 35-950 GHz is the largest existing telescope array in the world. Among the 10 receiver bands, Band-1, which covers 35-50 GHz, is the lowest. Due to its small dimension and its
Band-1 receiver front-end cartridges for Atacama Large Millimeter/submillimeter Array (ALMA): design and development toward production
The ALMA Band-1 receiver front-end prototype cold and warm cartridge assemblies, including the system and key components for ALMA Band-1 receivers have been developed and two sets of prototype
Spinning Dust Emission from Circumstellar Disks and Its Role In Excess Microwave Emission
Electric dipole emission from rapidly spinning polycyclic aromatic hydrocarbons (PAHs) is widely believed as an origin of anomalous microwave emission (AME), but recently it encounters a setback due
The Massive and Distant Clusters of WISE Survey
Context. The Massive and Distant Clusters of WISE Survey (MaDCoWS) provides a catalog of high-redshift (0.7 ≲ z ≲ 1.5) infrared-selected galaxy clusters. However, the verification of the ionized
The ALMA Development Program: Roadmap to 2030
The Atacama Large Millimeter/submillimeter Array (ALMA) is the premier telescope for sensitive, high-resolution observations at millimeter and submillimeter wavelengths. The array consists of fifty
Anomalous Microwave Emission from Star Forming Regions
The evidence for microwave emission from spinning dust grains has been strengthened considerably by its detection in a number of discrete astrophysical objects associated with star formation. These

CARMA Measurements of the Sunyaev-Zel'dovich Effect in RX J1347.5?1145
We demonstrate the Sunyaev-Zel'dovich (SZ) effect imaging capabilities of the Combined Array for Research in Millimeter-wave Astronomy (CARMA) by presenting an SZ map of the galaxy cluster RX
The Atacama Cosmology Telescope (ACT): Beam Profiles and First SZ Cluster Maps
The Atacama Cosmology Telescope (ACT) is currently observing the cosmic microwave background with arcminute resolution at 148 GHz, 218 GHz, and 277 GHz. In this paper, we present ACT's first results.

We present a detailed analysis from new multi-wavelength observations of the exceptional galaxy cluster ACT-CL J0102-4915 "El Gordo," likely the most massive, hottest, most X-ray luminous and
X-ray emission from clusters of galaxies
We present a summary of X-ray spectral observations of ~ 30 clusters of galaxies from HEAO-1. There exists strong correlations between X-ray luminosity, Lx, and temperature kT in the form Lx ∝ T2.3.

The hot, diffuse gas that fills the largest overdense structures in the Universe -- clusters of galaxies and a web of giant filaments connecting them -- provides us with tools to address a wide array
Planck early results - VIII. The all-sky early Sunyaev-Zeldovich cluster sample
We present the first all-sky sample of galaxy clusters detected blindly by the Planck satellite through the Sunyaev-Zeldovich (SZ) effect from its six highest frequencies. This early SZ (ESZ) sample
Precipitable Water at the VLA | 1990 { 1998
The amount of water vapor in the atmosphere above the VLA is an interesting quantity for two reasons: water vapor contributes signi cantly to the opacity of the atmosphere, and the uctuations in
Galaxy clusters and the cosmic cycle of baryons across cosmic times
We discuss the central role played by the X-ray study of hot baryons within galaxy clusters to reconstruct the assembly of cosmic structures and to trace the past history of star formation and
Atmospheric Opacity at the VLA VLA Test Memo 232
It is important to quantify the atmospheric opacity at the VLA in order to aid in interpretation of data taken at high frequencies. In addition, in the near future it is envisioned that dynamic
