We present cosmological results from the measurement of baryon acoustic oscillations (BAO) in galaxy, quasar and Lyman-$\alpha$ forest tracers first year observations Dark Energy Spectroscopic Instrument (DESI), to be released DESI Data Release 1. BAO provide robust measurements transverse comoving distance Hubble rate, or their combination, relative sound horizon, seven redshift bins over 6 million extragalactic objects range $0.1<z<4.2$. data alone are consistent with standard flat...
Abstract We present the DESI 2024 galaxy and quasar baryon acoustic oscillations (BAO) measurements using over 5.7 million unique redshifts in range 0.1 < z 2.1. Divided by tracer type, we utilize 300,017 galaxies from magnitude-limited Bright Galaxy Survey with 0.4, 2,138,600 Luminous Red Galaxies 0.4 1.1, 2,432,022 Emission Line 0.8 1.6, 856,652 quasars 2.1, a ∼ 7,500 square degree footprint. The analysis was blinded at catalog-level to avoid confirmation bias. All fiducial choices of...
Abstract Baryon acoustic oscillations (BAO) provide a robust standard ruler to measure the expansion history of Universe through galaxy clustering. Density-field reconstruction is now widely adopted procedure for increasing precision and accuracy BAO detection. With goal finding optimal settings be used in DESI 2024 analysis, we assess sensitivity post-reconstruction constraints different choices our analysis configuration, performing tests on blinded data from first year observations (DR1),...
Abstract A critical requirement of spectroscopic large scale structure analyses is correcting for selection which galaxies to observe from an isotropic target list. This often limited by the hardware used perform survey will impose angular constraints simultaneously observable targets, requiring multiple passes all them. In SDSS this manifested solely as collision physical fibers and plugs placed in plates. DESI, there additional constraint robotic positioner controls each fiber being a...
Abstract In the era of precision cosmology, ensuring integrity data analysis through blinding techniques is paramount — a challenge particularly relevant for Dark Energy Spectroscopic Instrument (DESI). DESI represents monumental effort to map cosmic web, with goal measure redshifts tens millions galaxies and quasars. Given volume impact findings, potential confirmation bias poses significant challenge. To address this, we implement validate comprehensive blind strategy Data Release 1 (DR1),...
We present the measurements and cosmological implications of galaxy two-point clustering using over 4.7 million unique quasar redshifts in range $0.1<z<2.1$ divided into six redshift bins a $\sim 7,500$ square degree footprint, from first year observations with Dark Energy Spectroscopic Instrument (DESI Data Release 1). By fitting full power spectrum, we extend previous DESI DR1 baryon acoustic oscillation (BAO) to include redshift-space distortions signals matter-radiation equality scale....
The study corresponds the role played by AKARI-II for exploring lives of stars in space.AKARI-II officially famous as ASTRO-F, launched on 21 February, 2006 is second Japanese satellite a space mission to carry out sky-high observations using infrared technology.It has telescope fitted with an Infrared camera which spectral range 2-26 µm and Far-Infrared Surveyor 50-180 µm.The mirror made up sandwich type silicon carbide, kept cool 180 L liquid Helium sensitive observations.AKARI performs...
