Denis Burgarella (LAM, Marseille, France):

24 April 2020, Observational and theoretical constraints on the formation and early evolution of the first dust grains in galaxies at 5 < z < 10.

This talk will present a new paper in press (observations and modelling) on the detection of the first dust grains in the early universe and what this could imply on future IR/sub-mm observations.

Pierre Cox (IAP, Paris, France):

18 May 2020, Redshift measurements of Bright Herschel galaxies: the IRAM/NOEMA Large Program z-GAL.

This talk will present the IRAM/NOEMA Large Program z-GAL and a previous pilot program. Both study dust-obscured, bright, high-redshift, Herschel-detected galaxies.

Tsutomu Takeuchi (Univ. Nagoya, Japan):

18 May 2020, New SED model consistent with chemical evolution and nonlinear dust evolution.

This talk will present the last results from the Nagoya team on the chemical evolution of dust in galaxies and theoretical models to treat the non-linear evolution of dust grains.

Ken Osato (IAP, Paris, France):

18 June 2020, Perturbation theory challenge for Cosmology.

This talk will present the latest development of the perturbation theory to constrain cosmological parameters.

18 June 2020, ATHENA X-IFU.

This talk will present the status of the ESA mission ATHENA and more specifically the X-IFU instrument in Europe and in Japan.

Toru Yamada (ISAS/JAXA, Japan):

22 July 2020, Deep variability survey by SUBARU HSV.

This talk study variability of active galactic nuclei (AGNs) by using the deep optical multiband photometry data obtained from the Hyper Suprime-Cam Subaru Strategic Program (HSC SSP) survey in the COSMOS field.

Tom Bakx (University of Nagoya, Japan):

22 July 2020, [CII] and warm dust in an LBG at z = 8.31.

This talk report on the detection of the [C II] 157.7 micron emission from the Lyman break galaxy (LBG) MACS0416_Y1 at z = 8.3113, by using ALMA.

Jana Bogdanoska (LAM, Marseille, France):

23 September 2020, UV dust attenuation as a function of Mstar and redshift.

This work gives evidence to a redshift evolution of the dust attenuation-stellar mass relationship, as is suggested by recent works in the highest redshift range.

Yu Zhou (ISAS/JAXA, Japan):

23 September 2020, Can Warm-hot Intergalactic Medium Account for the Spatial Fluctuation of the Soft Diffuse X-ray Background?

The Universe is evolving from the big bang to the present, it predicts that the averaged temperature of the matter at inter galactic space is growing up above million kelvins, and is shining in X-ray.

Anton Dmytriiev (LUTH, Paris-Meudon, France):

17 November 2020, Connecting steady emission and Very High Energy flaring states in blazars: the case of Mrk 421.
