PHANGS HST & JWST

Physics at High Angular resolution in Nearby GalaxieS

ABOUT PHANGS HST & JWST



PHANGS (Physics at High Angular resolution in Nearby GalaxieS) has conducted the
principal ALMA Large Program for nearby galaxies, and has obtained CO (2-1) maps
for a complete sample of 74 spiral galaxies. HST and JWST imaging spanning from
the near-UV to 21 microns for all 74 galaxies is being obtained through five
PHANGS programs:

 * HST Treasury (2019-21 PI: JC Lee)
 * JWST Treasury (2022-24 PI: JC Lee)
 * HST H-alpha Treasury (2023-24 PI: R Chandar)
 * HST2 Treasury (2023-24 PI: D Thilker)
 * JWST2 Treasury (2023-24 PI: A Leroy)
 * HST H-alpha (2024 PI: F Belfiore)



The combination of these surveys provide the first dataset to enable the
multi-phase, multi-scale study of star formation across spiral galaxies in the
local universe, from star clusters and molecular clouds to galactic disks.

Funding shortfall for Hubble impacts PHANGS science

NEW !

 



Due to a severe reduction in NASA funding for HST programs, we regret to
announce that high level image and catalog products will not be released from
PHANGS-HST2 (GO-17502), which is supported at a per-orbit-level ~4 times lower
than the original PHANGS-HST Treasury program (GO-15654). Funded PHANGS-HST2
activities will focus on science analysis of star clusters, and will exclude the
study of multi-scale associations and HII regions that was described in the
approved proposal.

PHANGS Press and Data release

NEW !

 



On Monday January 29th 2024 there was a press and data release for
PHANGS-HST-JWST

PHANGS-JWST ApJL First Results Special Issue

 



PHANGS JWST First Results JWST is revolutionizing fields across astrophysics,
and chief among them is the study of the earliest stages of star formation and
the dusty interstellar medium (ISM). On February 2023, a special issue of the
Astrophysical Journal Letters was printed to celebrate the first results.

JWST CYCLE 1 TREASURY PROGRAM



A JWST Cycle 1 Treasury Program to image 19/38 galaxies with full coverage by
ALMA/MUSE/HST with NIRCAM and MIRI has been approved. A January 2022 article
entitled Capturing All That Glitters in Galaxies With NASA’s Webb provides an
overview of the PHANGS-JWST survey understandable to the public.

PHANGS-CAT Data Release 1 (2022)

 



PHANGS-CAT DR1 at MAST provides catalogs for compact clusters and a separate set
of catalogs for multi-scale associations for five galaxies: NGC 1433, NGC 1566,
NGC 1559, NGC 3351, and NGC 3627. Please see the PHANGS-CAT site at MAST for
more information.

PHANGS-HST Data Releases 1 & 2 (2021)



 



PHANGS-HST DR1 & DR2 at MAST provides imaging for all 38 galaxies in the sample,
as well as visualization tools, and neural network models for star cluster
morphological classification. Please see the PHANGS HST site at MAST for more
information.

HST and ALMA: Probing the life-cycle of star formation regions




PHANGS-HST and PHANGS-ALMA observations of the nearby spiral galaxy NGC1559. The
high angular resolution afforded by HST allows for the identification of
individual young star clusters that have just emerged from their birth cloud as
seen by ALMA.

NGC 1559 in optical light: white light (red), H-band (green), NUV (blue)
NGC 1559 in optical light with molecular gas distribution added in red.
The molecular gas distribution from ALMA is remarkably similar to the dust lanes
seen in optical light.
