			*Dust geometry in nearby disk galaxies
			: Speaker: Jiafeng Lu
			: By analyse spectrum of 150000 disk galaxies in SDSS, we find a difference between extinction of emission and extinction of continuum. Then we give a quantitative estimation of dust geometry to explain it. We also check the rationality of our conclusions with MaNGA data.

	: Abstract: Wolf-Rayet (WR) galaxies are defined as galaxies presenting broad emission lines of He/C/N in their spectra. This reflects the existence of WR stars, a population of very massive and short-lived stars (<10 Myr). We intend to use WR galaxies in MaNGA for constraining the initial mass function. The catalog consists of 90 WR galaxies containing ~~254~~ WR regions. We have finished analyzing most of the host galaxy properties such as mass-metallicity relation. We have also carried out spatially resolved analysis and WR feature fitting. We will present the catalog and the analysis so far.		: Abstract: Wolf-Rayet (WR) galaxies are defined as galaxies presenting broad emission lines of He/C/N in their spectra.

	: Abstract: We collate and summarize the observed galaxies of ALMA telescope, and establish a galaxy molecular gas sample with pretty high resolution. Then matching it with the existing MaNGA and Herschel Galaxy catalogues to find the same galaxies included in all three catalogues for subsequent multi-wavelength research. By sorting and marching, there are 133 galaxies with both ALMA and Herschel observations, and 29 with both ALMA and Sloan/MaNGA observations. The merging galaxy NGC2623 is found to have observations in all 3 bands.		: Abstract: We collate and summarize the observed galaxies of ALMA telescope, and establish a galaxy molecular gas sample with pretty high resolution.

	: Abstract: We investigate the dust attenuation in galaxy mergers using the multiwavelength photometry from the ultraviolet (UV) to the infrared (IR), and MaNGA's integral field spectroscopy. Comparing the dust attenuation derived from the UV-to-IR data and the optical data, we find that the difference is consistent with the picture that younger stellar populations are attenuated by an additional dust component from the birth clouds compared to older stellar populations which are only attenuated by the diffuse dust. Our results suggest that the two-component dust model is more robust to reconstruct the SFH of the galaxy merger than the simple one-component dust model.		: Abstract: We investigate the dust attenuation in galaxy mergers using the multiwavelength photometry from the ultraviolet (UV) to the infrared (IR), and MaNGA's integral field spectroscopy.

	:Abstract: I will present a new analysis of the environment of MaNGA galaxies, examining the correlation of star formation cessation in MaNGA galaxies as indicated by D4000, EW(Halpha) and EW(Hdelta_A) with their environment. For environment we consider the central/satellite division, the local density and the host dark matter halo mass. I will show that central and satellite galaxies show different quenching status even when stellar mass and halo mass are limited to a narrow range.		:Abstract: I will present a new analysis of the environment of MaNGA galaxies, examining the correlation of star formation cessation in MaNGA galaxies as indicated by D4000, EW(Halpha) and EW(Hdelta_A) with their environment.

	: Abstract: As the smallest, least luminous, however most common systems in the universe, dwarf galaxies have come to play an increasingly important role in understanding how galaxies form and evolve.We use a Bayesian inference code to analyze the IFU data-cubes of low mass galaxies in MaNGA, aiming to examine the star formation history of those galaxies. We focus on whether we can find hints of the hidden old stellar population in the low mass dwarfs, how the assumed SFH model would bias the inference of stellar properties, and how the SFHs vary within a single galaxy and between different galaxies.		: Abstract: As the smallest, least luminous, however most common systems in the universe, dwarf galaxies have come to play an increasingly important role in understanding how galaxies form and evolve.We use a Bayesian inference code to analyze the IFU data-cubes of low mass galaxies in MaNGA, aiming to examine the star formation history of those galaxies.
