“…The extragalactic background light at far-infrared wavelengths comes from optically faint, dusty, star-forming galaxies in the Universe with star formation rates of a few hundred solar masses per year4. These faint, submillimetre galaxies are challenging to study individually because of the relatively poor spatial resolution of far-infrared telescopes. …”

A mass of less than 15 solar masses for the black hole in an ultraluminous X-ray source by Motch, C., Pakull, M., Soria, Roberto, Grisé, F., Pietrzynski, G.

“…By modelling the strong optical and ultraviolet modulations arising from X-ray heating of the B9Ia donor star, we constrain the black hole mass to be less than 15 solar masses. Our results demonstrate that in P13, soft thermal emission and spectral curvature are indeed signatures of supercritical accretion. …”

The First Planetary Microlensing Event with Two Microlensed Source Stars by Bennett, D., Udalski, A., Han, C., Bond, I., Beaulieu, J., Skowron, J., Gaudi, B., Koshimoto, N., Abe, F., Asakura, Y., Barry, R., Bhattacharya, A., Donachie, M., Evans, P., Fukui, A., Hirao, Y., Itow, Y., Li, M., Ling, C., Masuda, K., Matsubara, Y., Muraki, Y., Nagakane, M., Ohnishi, K., Oyokawa, H., Ranc, C., Rattenbury, N., Rosenthal, M., Saito, T., Sharan, A., Sullivan, D., Sumi, T., Suzuki, D., Tristram, P., Yonehara, A., Szymanski, M., Poleski, R., Soszynski, I., Ulaczyk, K., Wyrzykowski, Depoy, D., Gould, A., Pogge, R., Yee, J., Albrow, M., Bachelet, E., Batista, V., Bowens-Rubin, R., Brillant, S., Caldwell, J., Cole, A., Coutures, C., Dieters, S., Prester, D., Donatowicz, J., Fouqué, P., Horne, K., Hundertmark, M., Kains, N., Kane, S., Marquette, J., Menzies, J., Pollard, K., Ranc, C., Sahu, K., Wambsganss, J., Williams, Andrew, Zub, M.

“…Thus, the system resembles a half-scale model of the Sun-Jupiter system with a half-Jupiter0mass planet orbiting a half-solar-mass star at very roughly half of Jupiter's orbital distance from the Sun. …”

Is the observed high-frequency radio luminosity distribution of QSOs bimodal? by Mahony, E., Sadler, E., Croom, S., Ekers, Ronald, Feain, I., Murphy, T.

“…However, if the radio emission was solely due to star formation processes, we calculate that this corresponds to star formation rates ranging from ~10 solar masses/yr to ~2300 solar masses/yr.…”

From starburst to quiescence: the rapid evolution of galaxies within the large-scale structure by Wilkinson, Aaron K.R.

“…SMGs are extremely active dust-obscured galaxies in the early Universe, forming stars with an immense rate of up to 1000 solar masses per year. PSB galaxies are characterised by strong Balmer absorption lines in their spectra, consistent with a recent burst of star formation before being rapidly quenched. …”

Super-Eddington Mechanical Power of an Accreting Black Hole in M83 by Soria, Roberto, Long, K., Blair, W., Godfrey, L., Kuntz, K., Lenc, E., Stockdale, C., Winkler, P.

“…Its accretion disk properties indicate that this black hole is less than 100 solar masses. The optical/IR line emission implies an average kinetic power of 3 × 10 40 erg second-1, higher than the Eddington luminosity of the black hole. …”

The closest extremely low-mass white dwarf to the Sun by Kawka, Adela, Simpson, Jeffrey D, Vennes, Stephane, Bessell, Michael S, Da Costa, Gary S, Marino, Anna F, Murphy, Simon J

“…We find that this star is hydrogen-rich with Teff ~ 10 500 K, log g ~ 5.9, and, following evolutionary models, has a mass of ~ 0.17 solar masses. Independent analysis of radial velocity and TESS photometric time series reveals an orbital period of ~ 9.5 h. …”

An extreme magneto-ionic environment associated with the fast radio burst source FRB 121102 by Michilli, D., Seymour, A., Hessels, J., Spitler, L., Gajjar, V., Archibald, A., Bower, G., Chatterjee, S., Cordes, J., Gourdji, K., Heald, G., Kaspi, V., Law, C., Sobey, Charlotte, Adams, E., Bassa, C., Bogdanov, S., Brinkman, C., Demorest, P., Fernandez, F., Hellbourg, G., Lazio, T., Lynch, R., Maddox, N., Marcote, B., McLaughlin, M., Paragi, Z., Ransom, S., Scholz, P., Siemion, A., Tendulkar, S., Van Rooy, P., Wharton, R., Whitlow, D.

“…Such large rotation measures have hitherto been observed only in the vicinities of massive black holes (larger than about 10,000 solar masses). Indeed, the properties of the persistent radio source are compatible with those of a low-luminosity, accreting massive black hole. …”

The interstellar medium in high-redshift submillimeter galaxies as probed by infrared spectroscopy by Wardlow, J.L., Cooray, A., Osage, Willow, Bourne, Nathan, Clements, David, Dannerbauer, Helmut, Dunne, Loretta, Dye, S., Eales, S., Farrah, Duncan, Furlanetto, C., Ibar, E., Ivison, Rob J., Maddox, S., Michałowski, Michał M., Riechers, Dominik, Rigopoulou, D., Scott, Douglas, Smith, M.W.L., Wang, Lingyu, van der Werf, Paul, Valiante, Elisabetta, Valtchanov, I., Verma, Aprajita

“…Submillimeter galaxies (SMGs) at are luminous in the far-infrared, and have star formation rates, SFR, of hundreds to thousands of solar masses per year. However, it is unclear whether they are true analogs of local ULIRGs or whether the mode of their star formation is more similar to that in local disk galaxies. …”

The growth of the first galaxies by Duncan, Kenneth James

“…Integrating our new mass functions, we find the observed stellar mass density evolves from log10(rho) = 6.64 +0.58/-0.89 at z ~ 7 to 7.36 +/- 0.06 solar masses per Mpc^-3 at z ~ 4. Combining the measured UV continuum slopes (beta) with their rest-frame UV luminosities, we calculate dust corrected star-formation rates (SFR) for our sample. …”
