  1. 41. Welcome
    Dr Cullan Howlett (The University of Queensland)
    2/3/25, 8:30 AM
  2. 54. Mapping Mass and Motion in the Local Universe with 4HS
    Edward Taylor (Swinburne University of Technology)
    2/3/25, 8:50 AM

    I will give a brief overview of the 4MOST Hemisphere Survey (4HS), with particular emphasis on our cosmology science goals of mapping mass and motion on ~Gpc scales, and highlighting several key aspects of the 4HS experimental design relative to past and current surveys.

  3. 55. DESI, an overview, peculiar velocities and synergies with ZTF
    Julian Ernesto BAUTISTA
    2/3/25, 9:20 AM

    In this talk I will give an overview of the Dark Energy Spectroscopic Instrument (DESI) and their first cosmological results from the first-year dataset. I will briefly introduce the DESI peculiar velocity program, aiming the measurement of 180k distances with Tully-Fisher and Fundamental Plane relations. I will also briefly introduce the Zwicky Transient Facility (ZTF) and their supernovae...

  4. 8. Optimising 4MOST survey strategy for peculiar velocity surveys
    Prof. Elmo Tempel (University of Tartu)
    2/3/25, 9:50 AM

    4MOST is a next-generation survey that will start operating in 2025 and will carry out a five-year survey program. 4MOST consists of 18 individual surveys that will be operationally carried out as a single survey. Among those 18 surveys, there are specific peculiar velocity subsurveys that will significantly extend currently available catalogues of peculiar velocities. To optimise the 4MOST...

  5. 43. A High-Statistics Tully-Fisher Catalog using Fiber Spectroscopy
    Dr Segev BenZvi (University of Rochester)
    2/3/25, 10:10 AM

    The Tully-Fisher relation (TFR) is an empirical correlation between the instrinsic luminosity of a spiral galaxy and its asymptotic rotational velocity. Here we present measurements of the TFR from a secondary target program at the Dark Energy Spectroscopic Instrument, a robotic fiber-fed spectrograph located at Kitt Peak National Observatory. By positioning fibers on the galaxies' nuclei and...
