  • The completed SDSS-IV extended baryon oscillation spectroscopic survey: BAO and RSD measurements from the anisotropic power spectrum of the quasar sample between redshift 0.8 and 2.2 
    Neveux, Richard; Burtin, Etienne; Mattia, Arnaud de; Smith, Alex; Ross, Ashley J; Hou, Jiamin; Bautista, Julian; Brinkmann, Jonathan; Chuang, Chia-Hsun; Dawson, Kyle S; Gil-Marin, Hector; Lyke, Brad W; Macorra, Axel de la; Bourboux, Helion du Mas des; Mohammad, Faizan G; Muller, Eva-Maria; Myers, Adam D; Newman, Jeffrey A; Percival, Will J; Rossi, Graziano; Schneider, Donald; Vivek, M; Zarrouk, Pauline; Zhao, Cheng; Zhao, Gong-Bo (Oxford University Press on behalf of the Royal Astronomical Society, 2020-11)
    We measure the clustering of quasars of the final data release (DR16) of eBOSS. The sample contains 343708 quasars between redshifts 0.8 ≤ z ≤ 2.2 over 4699deg2⁠. We calculate the Legendre multipoles (0,2,4) of the anisotropic ...
  • Signatures of Light Massive Relics on non-linear structure formation 
    Banerjee, Arka; Das, Subinoy; Maharana, Anshuman; Sharma, R. K (Oxford University Press on behalf of Royal Astronomical Society, 2022-10)
    Cosmologies with Light Massive Relics (LiMRs) as a subdominant component of the dark sector are well-motivated from a particle physics perspective, and can also have implications for the σ8 tension between early and late ...
  • The WIRCAM Deep Infrared Cluster Survey I. Groups and clusters at z  ≳  1.1 
    Bielby, R. M; Finoguenov, A; Tanaka, M; McCracken, H. J; Daddi, E; Hudelot, P; Ilbert, O; Kneib, J. P; Le Fèvr, O; Mellier, Y; Nandra, K; Petitjean, P; Srianand, R; Stalin, C. S; Willott, C. J (EDP Sciences, 2010-12)
    We use a combination of CFHTLS deep optical data, WIRcam Deep Survey (WIRDS) near-infrared data and XMM-Newton survey data to identify z ≳ 1.1 clusters in the CFHTLS D1 and D4 fields. Counterparts to such clusters can not ...
