Dusty star-forming galaxies (DSFGs) contribute significantly to the stellar buildup at cosmic noon. Major mergers and gas accretion are often invoked to explain DSFGs' prodigious star-formation rates (SFRs) and large stellar masses. We conducted a sp

OJ287 is a quasi-periodic quasar with roughly 12 year optical cycles. It displays prominent outbursts which are predictable in a binary black hole model. The model predicted a major optical outburst in December 2015. We found that the outburst did oc

The Dependence of the $A_V$ Prior for SN\,Ia on Host Mass and Disk Inclination

Autor: Holwerda, B. W., Keel, W. C., Kenworthy, M. A., Mack, K. J.

Supernovae type Ia (SNIa) are used as "standard candles" for cosmological distance scales. To fit their light curve shape -- absolute luminosity relation, one needs to assume an intrinsic color and a likelihood of host galaxy extinction or a convolut

The Occulting Galaxy Pair UGC 3995; Dust properties from HST and CALIFA data

Autor: Holwerda, B. W., Keel, W. C.

UGC 3995 is an interacting and occulting galaxy pair. UGC 3995B is a foreground face-on spiral and UGC 3995A a bright background spiral with an AGN. We present analysis of the dust in the disc of UGC 3995B based on archival Hubble Space Telescope WFP
