Puzia Pontificia Universidad Catolica de Chile N CoI: Dr. Thomas M. Brown Space Telescope Science Institute N ------------------------------------------------------------------------------------ Abstract Recent spectroscopic studies of nearby early-type galaxies (ETGs) revealed unexpected stellar population properties, with light-element abundance ratios [N/Fe] and [Na/Fe] that increase with galaxy mass. This galaxy mass dependence is reminiscent of the "UV upturn" at far-UV wavelengths in ETGs, which is produced by very hot (Teff > 20, 000 K) extreme horizontal branch stars that likely have supersolar helium abundances. We propose to test the hypothesis that these mass-dependent light-element abundance varations in He, N, and Na within and among ETGs are physically connected and produced by dissolution of relatively massive, metal-rich globular clusters (GCs), since the latter objects represent the only galactic environment where mass-dependent enrichment of He, N, and Na is known to occur (the "multiple stellar populations" phenomenon). To this end, we propose to obtain deep WFC3/UVIS images of a representative sample of nearby ETGs, spanning the observed range of UV upturn strengths. We will use the F275W and F390W passbands, which provide sensitive probes of the abundances of He and N in integrated-light measurements. When combined with existing archival ACS optical photometry of the same galaxies, we will be able to characterize the enrichment of He and N as a function of galactocentric radius and ETG mass, and in their GC populations themselves as well. This study will be the first to evaluate the level of He- and N-enrichment of the inner regions of ETGs by stars that escaped from massive GCs, which could provide an eye-opening, yet simple, explanation of both the UV upturn and the non-solar abundance ratios of light elements seen in the central regions of ETGs. ------------------------------------------------------------------------------------ Observations Description ------------------------ For the galaxies with 11 orbits worth of imaging with F275W and F390W, we split up the exposures as follows: (1) five 2-orbit visits, each of which do two long dithered F275W exposures per orbit. Each dithered exposure sequence uses POS TARGs relative to one another in order to improve PSF sampling and jump the chip gap. The last such visit includes one F390W image that will be combined with the three F390W exposures in the 1-orbit visit described next; (2) one 1-orbit visit with one medium-length F275W exposure and three dithered F390W exposures. 17756( 11) - 12-Sep-2025 00:49:05 - [ 2] For the galaxies with 3 or 4 orbits worth of imaging with F275W and F390W, we split up the exposures as follows: (1) two or three 1-orbit visits, each of which do two long dithered F275W exposures per orbit. Each dithered exposure sequence uses POS TARGs relative to one another in order to improve PSF samplin and jump the chip gap. The last such visit includes one F390W image that will be combined with the three F390W exposures in the 1-orbit visit described next; (2) one 1-orbit visit with one medium-length F275W exposure and three dithered F390W exposures. The visits of each target galaxy are linked by using the ORIENT FROM XXX BY -10 TO 10 visit orientation requirement, as requested in the Phase I proposal. Each exposure uses the FLASH optional parameter in order to reach a background level of (at least) 20 e- to mitigate CTE losses. ------------------------------------------------------------------------------------ 17756( 11) - 12-Sep-2025 00:49:05 - [ 3] TARGET LIST Fixed Targets ------------------------------------------------------------------------------------------------------------------------------------ Tar| Target | Target | Target |Coord | Radial | Flux data No | Name | Description | Position |Eqnx | Vel. | ------------------------------------------------------------------------------------------------------------------------------------ 1 NGC-1399 GALAXY, ELLIPTICAL RA=03H38M29.0830S, J2000 V = 9.59 DEC=-35D27'2.67" Reference Frame: ICRS Comments: This object was generated by the targetselector and retrieved from the SIMBAD database. ------------------------------------------------------------------------------------------------------------------------------------ 2 NGC-4649 GALAXY, ELLIPTICAL RA=12H43M37.9035S, J2000 V = 8.84 DEC=+11D33'3.17" Reference Frame: ICRS Comments: This object was generated by the targetselector and retrieved from the SIMBAD database. ------------------------------------------------------------------------------------------------------------------------------------ 7 NGC-4649-COP GALAXY, ELLIPTICAL RA=12H43M38.0412S, J2000 V = 8.84 Y DEC=+11D32'53.10" Reference Frame: ICRS Comments: This object was generated by the targetselector and retrieved from the SIMBAD database.
