Observational Evidence from Supernovae for an Accelerating Universe and a Cosmological Constant
- A. Riess, A. Filippenko, J. Tonry
- Physics
- 15 May 1998
We present spectral and photometric observations of 10 Type Ia supernovae (SNe Ia) in the redshift range 0.16 ≤ z ≤ 0.62. The luminosity distances of these objects are determined by methods that…
The SBF Survey of Galaxy Distances. IV. SBF Magnitudes, Colors, and Distances
- J. Tonry, A. Dressler, C. B. Moore
- Physics
- 10 November 2000
We report data for I-band surface brightness fluctuation (SBF) magnitudes, (V-I) colors, and distance moduli for 300 galaxies. The survey contains E, S0, and early-type spiral galaxies in the…
The ACS Virgo Cluster Survey. XIII. SBF Distance Catalog and the Three-dimensional Structure of the Virgo Cluster
- S. Mei, J. Blakeslee, D. Merritt
- Physics
- 20 January 2007
The ACS Virgo Cluster Survey consists of HST ACS imaging for 100 early-type galaxies in the Virgo Cluster, observed in the F475W (≈SDSS g) and F850LP (≈SDSS z) filters. We derive distances for 84 of…
Type Ia Supernova Discoveries at z > 1 from the Hubble Space Telescope: Evidence for Past Deceleration and Constraints on Dark Energy Evolution
- A. Riess, L. Strolger, Z. Tsvetanov
- Physics
- 23 February 2004
We have discovered 16 Type Ia supernovae (SNe Ia) with the Hubble Space Telescope (HST) and have used them to provide the first conclusive evidence for cosmic deceleration that preceded the current…
New Hubble Space Telescope Discoveries of Type Ia Supernovae at z ≥ 1: Narrowing Constraints on the Early Behavior of Dark Energy
- A. Riess, L. Strolger, D. Stern
- Physics
- 17 November 2006
We have discovered 21 new Type Ia supernovae (SNe Ia) with the Hubble Space Telescope (HST) and have used them to trace the history of cosmic expansion over the last 10 billion yr. These objects,…
The Pan-STARRS1 Surveys
- K. Chambers, E. Magnier, R. Wyse
- Geology
- 16 December 2016
Pan-STARRS1 has carried out a set of distinct synoptic imaging sky surveys including the $3\pi$ Steradian Survey and the Medium Deep Survey in 5 bands ($grizy_{P1}$). The mean 5$\sigma$ point source…
THE ACS FORNAX CLUSTER SURVEY. V. MEASUREMENT AND RECALIBRATION OF SURFACE BRIGHTNESS FLUCTUATIONS AND A PRECISE VALUE OF THE FORNAX–VIRGO RELATIVE DISTANCE
- J. Blakeslee, A. Jordán, M. West
- Physics
- 8 January 2009
We present (g475 − z850) color and z850-band surface brightness fluctuations (SBFs) measurements for 43 early-type galaxies in the Fornax cluster imaged with the Hubble Space Telescope Advanced…
The Complete Light-curve Sample of Spectroscopically Confirmed SNe Ia from Pan-STARRS1 and Cosmological Constraints from the Combined Pantheon Sample
- D. Scolnic, D. Jones, K. Smith
- PhysicsAstrophysical Journal
- 2 October 2017
We present optical light curves, redshifts, and classifications for spectroscopically confirmed Type Ia supernovae (SNe Ia) discovered by the Pan-STARRS1 (PS1) Medium Deep Survey. We detail…
The ACS Virgo Cluster Survey. VI. Isophotal Analysis and the Structure of Early-Type Galaxies
- L. Ferrarese, P. Côté, M. West
- Physics
- 14 February 2006
We present a detailed analysis of the morphology, isophotal parameters, and surface brightness profiles for 100 early-type members of the Virgo Cluster, from dwarfs (MB = -15.1 mag) to giants (MB =…
A THREE-DIMENSIONAL MAP OF MILKY WAY DUST
- G. Green, E. Schlafly, R. Wainscoat
- Physics
- 3 July 2015
We present a three-dimensional map of interstellar dust reddening, covering three-quarters of the sky out to a distance of several kiloparsecs, based on Pan-STARRS 1 (PS1) and 2MASS photometry. The…
