The 2dF Galaxy Redshift Survey (2dFGRS) is designed to measure redshifts for approximately 250-000 galaxies. This paper describes the survey design, spectroscopic observations, redshift measurements and data base. 2dFGRS uses multifibre spectrograph on Anglo-Australian Telescope, which capable of observing 400 objects simultaneously over a 2° diameter field. source catalogue revised extended version APM galaxy catalogue, targets are galaxies with extinction-corrected magnitudes brighter than...
We present a power-spectrum analysis of the final 2dF Galaxy Redshift Survey (2dFGRS), employing direct Fourier method. The sample used comprises 221 414 galaxies with measured redshifts. investigate in detail modelling selection, improving on previous treatments number respects. A new angular mask is derived, based revisions to photometric calibration. redshift selection function determined by dividing survey according rest-frame colour, and deducing self-consistent treatment k-corrections...
Purpose To address early and late treatment failures in older patients with diffuse large B-cell lymphoma (DLBCL), we designed a two-stage randomized trial of cyclophosphamide, doxorubicin, vincristine, prednisone (CHOP) versus rituximab plus CHOP (R-CHOP), second random assignment to maintenance (MR) or observation responding patients. Patients Methods Untreated DLBCL who were 60 years randomly assigned R-CHOP (n = 318) 314); 415 responders MR 207) 208). The primary end point was...

MOPP (mechlorethamine, vincristine, procarbazine, and prednisone) has been the standard treatment for Hodgkin's disease almost 20 years. In a randomized, multicenter trial, we compared three regimens of primary systemic therapy newly diagnosed advanced in Stages IIIA2, IIIB, IVA or IVB: (1) alone given 6 to 8 cycles, (2) alternating with ABVD (doxorubicin, bleomycin, vinblastine, dacarbazine) 12 (3) cycles. Patients first relapse after radiation were eligible. No additional was given. who...
We report the final redshift release of 6dF Galaxy Survey, a combined and peculiar velocity survey over southern sky (|b|>10 deg). Its 136,304 spectra have yielded 110,256 new extragalactic redshifts catalogue 125,071 galaxies making near-complete samples with (K, H, J, r_F, b_J) <= (12.65, 12.95, 13.75, 15.60, 16.75). The median is 0.053. Survey data, including images, spectra, photometry redshifts, are available through an online database. describe changes to information in database since...
We report on our search for microlensing towards the Large Magellanic Cloud (LMC). Analysis of 5.7 years photometry 11.9 million stars in LMC reveals 13 - 17 events.

The 2dF Galaxy Redshift Survey has now measured in excess of 160-000 galaxy redshifts. This paper presents the power spectrum distribution, calculated using a direct Fourier transform based technique. We argue that, within k-space region , shape this should be close to that linear density perturbations convolved with window function survey. and its convolving effect on estimate are analysed detail. By model spectra, we able fit power-spectrum data provide measure matter content Universe. Our...
We present a detailed analysis of the two-point correlation function, ξ(σ, π), from 2dF Galaxy Redshift Survey (2dFGRS). The large size catalogue, which contains ∼220 000 redshifts, allows us to make high-precision measurements various properties galaxy clustering pattern. effective redshift at our estimates are made is zs≈ 0.15, and similarly luminosity, Ls≈ 1.4L*. estimate redshift-space ξ(s), we measure length, s0= 6.82 ± 0.28 h−1 Mpc. also projected Ξ(σ), real-space ξ(r), can be fit by...
We compute the bispectrum of 2dF Galaxy Redshift Survey (2dFGRS) and use it to measure bias parameter galaxies. This quantifies strength clustering galaxies relative mass in Universe. By analysing 80 × 106 triangle configurations wavenumber range 0.1 < k 0.5 h Mpc−1 (i.e. on scales roughly between 5 30 h−1 Mpc) we find that linear is consistent with unity: b1= 1.04 ± 0.11, quadratic (non-linear) zero: b2=−0.054 0.08. Thus, at least large scales, optically selected do indeed trace underlying...
We have measured the equivalent width of Hα emission line for 11 006 galaxies brighter than Mb=−19 (ΩΛ= 0.7, Ωm= 0.3, H0= 70 km s−1 Mpc−1) at 0.05 < z 0.1 in 2dF Galaxy Redshift Survey (2dFGRS), fields 17 known galaxy clusters. The limited redshift range ensures that our results are insensitive to aperture bias, and residuals from night sky lines. use these measurements trace μ*, star formation rate normalized L*, as a function distance cluster centre, local projected density. find...
We present a detailed analysis of the field-galaxy luminosity function for five magnitude-limited redshift surveys. apply maximum-likelihood estimators which we demonstrate provide unbiased estimates spatially inhomogeneous distributions under assumption that is uncorrelated with position. A likelihood-ratio test devised can be used to assess whether specific functional forms acceptable fits observations. These methods, and asymptotic their errors, are checked against Monte Carlo...
The MACHO Project is a search for dark matter in the form of massive compact halo objects (MACHOs). Photometric monitoring millions stars Large Magellanic Cloud (LMC), Small (SMC), and Galactic bulge used to gravitational microlensing events caused by these otherwise invisible objects. Analysis first 2.1 yr photometry 8.5 million LMC reveals eight candidate events. This substantially more than number expected (~1.1) from lensing known stellar populations. timescales (t) range 34 145 days. We...
In a series of trials, doxorubicin, bleomycin, vinblastine, and dacarbazine (ABVD) mechlorethamine, vincristine, procarbazine, prednisone, vinblastine (MOPP/ABV) have been identified as effective treatments for Hodgkin's disease. We compared these regimens initial chemotherapy disease.Adult patients (N = 856) with advanced disease were randomly assigned to treatment ABVD or MOPP/ABV. The major end points failure-free overall survival, life-threatening acute toxicities, serious long-term...
