As Congress prepares to return to a monthlong sprint until the ⭐️funding deadline,
pressure will be on Chuck Schumer to hold his ground and tensions could significantly heighten.
Schumer and House Minority Leader Hakeem Jeffries (D-N.Y.) on Thursday called on their GOP counterparts to
“immediately meet” once Congress returns from recess next week
to discuss the need to avert a shutdown,
while pressing for their proposal to “fund the government in a bipartisan ma…

A Multi-Messenger Search for the Supermassive Black Hole Binary in 3C 66B with the Parkes Pulsar Timing Array
A sub-parsec supermassive black hole binary at the center of the galaxy 3C 66B is a promising candidate for continuous gravitational wave searches with Pulsar Timing Arrays. In this work, we search for such a signal in the third data release of the Parkes Pulsar Timing Array. Matching our priors to estimates of binary parameters from electromagnetic observations, we find log Bayes factor of 0.22, highlighting that the source can be neither confirmed nor ruled out. We place upper limits at 95% c…

Sonnet 104 - CIV
To me, fair friend, you never can be old,
For as you were when first your eye I ey'd,
Such seems your beauty still. Three winters cold,
Have from the forests shook three summers' pride,
Three beauteous springs to yellow autumn turn'd,
In process of the seasons have I seen,
Three April perfumes in three hot Junes burn'd,
Since first I saw you fresh, which yet are green.
Ah! yet doth beauty like a dial-hand,…

Reconstruction of X-Ray Afterglow Light Curves of GRBs and its implication for constraining Cosmological Parameters
Gamma-ray bursts (GRBs) serve as important cosmological probes, whose X-ray afterglow light curves (LCs) may exhibit a plateau phase (with temporal slope $α$ between 0 and 0.5) that may originate from magnetar energy injection. Similar to Type Ia Supernovae, GRBs with a common physical origin can be used as standardizable candles for cosmological studies. However, observational gaps in GRB light curves introduce significant uncertainties in plateau parameter estimation, thereby affecting cosmo…

Searching for continuous gravitational waves in the Parkes Pulsar Timing Array DR3
We present results from an all-sky search for continuous gravitational waves from individual supermassive binary black holes using the third data release (DR3) of the Parkes Pulsar Timing Array (PPTA). Even though we recover a common-spectrum stochastic process, potentially induced by a nanohertz gravitational wave background, we find no evidence of continuous waves. Therefore, we place upper limits on the gravitational-wave strain amplitude: in the most sensitive frequency range around 10 nHz,…

The NANOGrav 15 yr Data Set: Targeted Searches for Supermassive Black Hole Binaries
We present the first catalog of targeted searches for continuous gravitational waves (CWs) from 114 active galactic nuclei (AGN) that may host supermassive black hole binaries (SMBHBs), using the NANOGrav 15 yr data set. By incorporating electromagnetic priors on sky location, distance, redshift, and CW frequency, our strain and chirp mass upper limits are on average 2.6$\times$ more constraining than sky-averaged limits. Bayesian model comparisons against a common uncorrelated red noise for th…

Massive stars exploding in a He-rich circumstellar medium. XI. Diverse evolution of five Ibn SNe 2020nxt, 2020taz, 2021bbv, 2023utc and 2024aej
We present the photometric and spectroscopic analysis of five Type Ibn supernovae (SNe): SN 2020nxt, SN 2020taz, SN 2021bbv, SN 2023utc, and SN 2024aej. These events share key observational features and belong to a family of objects similar to the prototypical Type Ibn SN 2006jc. The SNe exhibit rise times of approximately 10 days and peak absolute magnitudes ranging from $-$16.5 to $-$19 mag. Notably, SN 2023utc is the faintest Type Ibn supernova discovered to date, with an exceptionally low r…
