Nemotron 3 Ultra: Open, Efficient Mixture-of-Experts Hybrid Mamba-Transformer Model for Agentic Reasoning
NVIDIA, :, Aaron Blakeman +571
We introduce Nemotron 3 Ultra, a 550 billion total and 55 billion active parameter Mixture-of-Experts Hybrid Mamba-Attention language model. We pre-trained Nemotron 3 Ultra on 20 t…
Cosmological Constraints from a 31 GHz Sky Survey with the Sunyaev-Zel'dovich Array
Stephen Muchovej, Erik Leitch, John E Carlstrom +13
We present the results of a 6.1 square degree survey for clusters of galaxies via their Sunyaev- Zel'dovich (SZ) effect at 31 GHz. From late 2005 to mid 2007 the Sunyaev-Zel'dovich…
Observations of High-Redshift X-Ray Selected Clusters with the Sunyaev-Zel'dovich Array
Stephen Muchovej, John E. Carlstrom, John Cartwright +14
We report measurements of the Sunyaev-Zel'dovich (SZ) effect in three high-redshift (0.89 < z < 1.03), X-ray selected galaxy clusters. The observations were obtained at 30 GHz duri…
LoCuSS: A Comparison of Sunyaev-Zel'dovich Effect and Gravitational Lensing Measurements of Galaxy Clusters
Daniel P. Marrone, Graham P. Smith, Johan Richard +19
We present the first measurement of the relationship between the Sunyaev-Zel'dovich effect signal and the mass of galaxy clusters that uses gravitational lensing to measure cluster…
Radio Sources from a 31 GHz Sky Survey with the Sunyaev-Zel'dovich Array
Stephen Muchovej, Erik Leitch, John E. Carlstrom +13
We present the first sample of 31-GHz selected sources to flux levels of 1 mJy. From late 2005 to mid 2007, the Sunyaev-Zel'dovich Array (SZA) observed 7.7 square degrees of the sk…
A Measurement of Arcminute Anisotropy in the Cosmic Microwave Background with the Sunyaev-Zel'dovich Array
Matthew K. Sharp, Daniel P. Marrone, John E. Carlstrom +13
We present 30 GHz measurements of the angular power spectrum of the cosmic microwave background (CMB) obtained with the Sunyaev-Zel'dovich Array. The measurements are sensitive to…
